Triumph`s New Tiger 800XC vs. BMW`s F800GS
Model Comparison Triumph’s New Tiger 800XC vs. BMW’s F800GS by Dave Searle & Scott Rousseau T RIUMPH TELLS Us it began work on the new mid-size Tiger in 2007. For reference, this is the same year the BMW F800GS was first revealed at the Milan EICMA Show, where it met with enormous enthusiasm, so the impetus for the Tiger’s creation is unlikely to be a coincidence. Although the F800GS didn’t make it stateside until 2009, making the Tiger’s likeness seem less like a copy, in 2011 with both bikes side-byside, it’s obvious that Triumph has made a serious effort to duplicate the essential look of the F800GS in the Tiger 800, right down to detail styling licks like the folds in its windshield. As a result, when riding the two machines, they feel so much alike that choosing between them can be a matter of splitting hairs. Of course, powered by a three-cylinder engine, as opposed to the BMW’s parallel twin, the Tiger has a distinctive character, but the BMW has clearly formed a template for Triumph’s engineers. In fact, with the benefit of hindsight and the impressions of the world’s motorcycle press as a critique of the BMW’s strengths and weaknesses, Triumph should have been expected to produce a superior product. But has it? That’s the question we’ll try to answer. The Defending Champion Essentially alone in its class until the Tiger appeared, the F800GS made a very attractive adventure bike. When riding off-road as “adventure-touring” implies, weight really matters, every pound increasing rider effort and making the penalty for imprecise lines greater. So the fact that the F800GS was 30 lbs. lighter than KTM’s svelte 990 Adventure and 56 lbs. less than its burly boxer brother, the R1200GS, was very significant. Also, compared to the air-cooled R1200GS with its protruding cylinder heads, the liquid-cooled 800GS motor is very slim and tidy, enabling it to fit through narrow gaps in terrain that would present an obstacle to its big brother. Although it would never be able to duplicate the amazing versatility of the R1200GS, which can double as a very comfortable high–speed sport-touring mount, the F800GS fills an important dual-sport niche between BMW’s 650cc singles and the GS boxers. The Challenger The Tiger 800 motor, although based on the 675 triples that power the Daytona 675 and Street Triple road-only models, is 12 AUGUST 2011 ● MOTORCYCLE CONSUMER NEWS 85% all-new. Added stroke ups its displacement to 799cc, while the motor is retuned to provide more low- and mid-range power than the 675 models at the expense of their high-winding rpm. The motor is carried in a steel tube chassis that’s reminiscent of the F800GS and the model is sold in two separate variations; a street version with a 19" front tire, slightly different ergonomics and shorter suspension travel (just like BMW’s oddly named 798cc F650GS) and the Tiger 800XC (tested here) with a 21" front wheel and longer travel. See our sidebar on the standard Tiger 800, which was very impressive in its own right at the Tigers’ official intro in the San Diego mountains. Motors—Tie The F800GS motor is based on the clever Rotax-built 798cc parallel twin first used in BMW’s F800S and ST models. Using a dummy connecting rod for clatter-free counterbalancing, the motor makes the same even-fire soundtrack as the bigger boxer engines in a very compact package. Torquey and smooth running below about 75 mph, beyond those speeds the engine will produce enough vibration that buzzing in the handlebars will eventually detract from rider comfort. Doing much more than simply plugging an existing motor into a different body style, BMW retuned the twin’s powerband for greater mid-range with shorter duration cams and rearranged the engine’s cylinder angle specifically for the GS application; lifting the cylinders back from a 30° forward tilt to just 8.3° inclination to provide clearance for a 21" front wheel. Naturally an all-new exhaust system was part of the package, and while the official 85 hp rating of the motor’s output had not changed, our dyno testing found a noticeable difference at the rear wheel—the GS making less power and torque: 74.22 hp and 50.98 lb.-ft. vs. 79.0 hp and 55.4 lb.-ft. in the F800ST (tested Sept. 2007). Using a bore and stroke of 82.0mm x 75.6mm, the motor features finger followers between the cams and lifters for greater durability, so that valve lash checks are needed only every 20,000 miles. This actuation system also allows tight included valve angles for an very efficient combustion chamber shape. To make full use of its fuel, BMW’s BMS-K fuel injection uses knock-sensors together with a high 12.0:1 compression ratio, and our gas mileage numbers this time nearly equalled those of our last F800GS, with an average of 52.7 mpg (vs. 53.0 previously) when ridden hard in a variety of conditions on paved roads—which is excellent. Off-road, it averaged 48.5 mpg, and with a 4.2 gal. gastank, it should be able to handle 200-mile distances even in the dirt. Throttle response and driveability are generally very good except for low rpm when the on/off transitions are abrupt, which is a noticeable liability when picking your way through rock gardens. The rest of the time, its behavior is hard to fault, backed with a growling exhaust note that reinforces the impression of seamless torque delivery. The rev-limiter intervenes at 8900 rpm, and although the dyno chart reveals a slightly lumpy power and torque delivery, these fluctuations aren’t noticeable when riding. The F800GS’ Rotax-built transmission is one of BMW’s best gearboxes. Shifting up or down requires only light effort, and the ratios seem ideal on the street. Off-road, there was some disagreement as the lower gears were more widely spaced than the Tiger’s. Backed with a cable-operated clutch which has a reach-adjustable lever, we found the clutch can be feathered when necessary to soften the motor’s abrupt low-speed power delivery without undue hand fatigue. The Tiger’s 800 motor, as mentioned, is 85% all-new. The clutch assembly is a carry-over, the valve sizes and head casting are the same but the combustion chambers are machined to give a lower compression ratio (reduced from the Street Triple’s 12.65:1 to 11.1:1 on the Tiger). The cylinder liners and pistons are also new, although they are the same bore size, and its new connecting rods are the same length as before. All the gear ratios except for second are brand-new as well. The throttle bodies are the same 44mm sizes, and Keihin continues to supply the fuel injection, although a new higher-capacity fuel rail handles the extra volume needed by the larger motor, and a new idle module was required to make it idle properly. Already a marvel of compact power in its 675cc configuration, a new crankshaft adds 9.6mm of stroke (now 61.9mm), combining with the same 74.0mm bore dimension to give a 799cc displacement. The cam timing is changed as well, with slightly lower lift and much shorter duration on the intakes for more lowand mid-range power, while the exhaust cam gives the same lift and almost as much duration as the Street Triple. The end result is 81.13 rear wheel hp @ 9900 rpm with 48.52 lb.-ft. of torque @ 8000 rpm, rev-limited at 9900 rpm. Compare this with the Street Triple’s much higher state of tune; 92.24 rwhp @ 11,750 rpm with 44.25 lb.-ft. @ 8250 rpm and a 12,200 rpm limiter. The three-cylinder motor is very smooth running and offers an elastic, tractable pull that works well both in the dirt and on the street. Although it doesn’t quite match the BMW twin for lowand mid-range torque, it has 1000 more rpm available, which provides a 6.91 hp advantage vs. the Beemer while giving up 2.46 lb.-ft. in peak torque. Over the road, in a side-by-side race, the two run almost dead even, and our quarter-mile times were extremely close, the BMW’s extra torque giving it a hair quicker 0-60 mph time: 3.94 sec. to the Tiger’s 4.08 sec., an advantage it held to the end of the quarter-mile; the BMW recording a 12.10 sec. @ 108.76 mph run to the Tiger’s best of 12.19 sec. @ 108.72 mph. They don’t get much closer than that. Also, the way the Tiger’s motor is mounted in its chassis is different. Unlike the Street Triple and similar to a motocrosser (and the F800GS), the Tiger has its swingarm pivot running through the back of its crankcase, minimizing the distance between the output sprocket and pivot shaft to improve suspension action and reduce chain slack variations with its long-travel suspension. Other changes include reverting to an oil sight glass in the crankcase and eliminating the dipstick. If the Tiger’s delightful triple has any downsides, two are worthy of mention. One is a disappointing tendency to stall unexpectedly when first given gas from a stop. Although it only happens maybe once in ten times, that’s often enough that you STANDARD TIGER 800 At the Tiger’s San Diego intro, we had the chance to try both the Tiger XC and the standard Tiger 800. With a 110/90ZR19 front tire (vs. a 90/9021 on the XC) for more front grip, shorter, non-adjustable suspension (travel 7.09" front/6.69" rear vs. 8.66" front/8.46" rear on the XC), the standard model sits lower on slightly altered steering geometry and wears a lower, narrower, more backswept handlebar (31.3" vs. 34" wide). With the same motor, same awesome brakes and slick transmission, the standard Tiger 800 is a twisty road terror. Its comfy upright riding position, excellent torque and traction feel when both accelerating and braking make it a spectacular sportbike for asphalt addicts. Visit us at WWW.MCNEWS.COM ● AUGUST 2011 13 Model Comparison roads at the same speeds. In the dirt, where the Tiger could be lugged smoothly at lower rpm, the gas mileage difference wasn’t as dramatic, the Triumph achieving 44.3 mpg to the BMW’s 48.5 mpg. But, unlike the BMW twin, vibration is never an issue with the Triumph triple. Suspensions & Chassis Geometry—Tiger 1st, GS 2nd soon find yourself attempting to compensate by giving the engine gas and then waiting a moment or two to verify it won’t stall before letting out the clutch. As the idle system is a new one, we suspect this is the source of the glitch and anticipate a remapping will be needed to correct the problem. The second issue is more subjective: an irritating exhaust sound. While it makes the typical diesel-like whirring that we expect and enjoy from a Triumph triple, once hot, it also makes a distracting pinging noise that we compare to pennies dropping into a coffee can. With earplugs in place, you barely notice it, but some riders complained vigorously at the new-model intro, so we shouldn’t discount its effect on sensitive ears. Asked for an explanation, we were told that because the catalytic convertor, where the noise originates, is directly under the engine, it’s more noticeable than when it emanates from an under-seat muffler, behind the rider. Also, that the sound results from a lean-burn mode built into the bike’s emission system that would otherwise require a complicated system of hoses and valves that would add weight and expense to the motor. None of MCN’s testers were put off by the Triumph’s sound, but that doesn’t mean you’ll feel the same. Make sure you hear it before you buy. We should also note that a majority of the Tigers at the intro were equipped with the optional Arrow slipon exhaust, a much lighter $500 option. The Arrow exhaust also made this same pinging, and the difference in sound output vs. the stocker was barely noticeable. However, the Arrow slip-on also contains a removable outlet restrictor that, if removed (and a new engine control map uploaded to the CPU), will add several hp as well as decibels. Transmissions—Tie Both the machines have exceptional transmissions, which offer low effort and slick engagements. Splitting hairs, we found the Triumph’s shift lever throw slightly shorter and its shift lever slightly longer, fitting our boots a bit better. Other than that, differences in their action are really too close to call. Although the F800GS shares the same gearbox ratios as the F800ST, it uses steeper 1:2.64 final drive sprockets (vs. the ST’s 1:2.35), so it spins a little faster at any given speed, turning 4300 rpm at a true 65 mph in top gear. But as the GS’ engine vibration becomes noticeable at higher speeds, we feel a taller sixth gear would be beneficial. The Triumph, as mentioned, has new ratios on five of its six transmission gears, only second gear unchanged from its Street Triple cogs. Its ratio spreads worked very well both on the street and on the dirt. Not surprisingly, the higher winding triple spins faster than the GS twin at a true 65 mph in top; 4490 rpm. This fact, plus the extra friction in a motor with 50% more reciprocating parts should account for the difference in fuel mileage we noted; the BMW was superior, with an excellent average mpg of 52.7 to the Triumph’s 45.6 mpg when ridden over the same 14 AUGUST 2011 ● MOTORCYCLE CONSUMER NEWS To make a 500-lb. dual-sport manageable off-road requires excellent suspension, and both these machines deliver the goods. The BMW wears a Marzocchi fork and a Sachs monoshock and has a touch more travel than the Triumph’s Showa components at both ends: 9.0" front/8.5" rear to the Tiger’s 8.66" front/8.46" rear. However, in a triumph (pun intended) of quality over quantity, we give the Tiger a clear edge in suspension, both on and off the road. Neither bike has an adjustable fork, so the stock settings have to be perfect. Alas, with what feels like slightly too soft springs and more compression damping than necessary, the BMW’s front end is just a bit less compliant and offers less feel for traction. In back, both machines wear adjustable monoshocks with handly external knob-controlled hydraulic preload and screwadjusted rebound adjustability. The Triumph’s Showa shock includes a large remote reservoir, which should improve its stamina in terms of resisting damping degradation on long off-road sections, and again we favored the Triumph’s rear suspension action. But the difference is not dramatic, and we were very pleased with the BMW until we rode the two back to back. But don’t imagine that the Tiger simply copies the GS’s chassis geometry, as Triumph clearly has its own ideas in this regard, the Brits typically giving us very fine handling machines with less rake and trail than average. The Tiger is no exception, using figures of 23.1° of rake with 3.59" of trail, to the BMW’s 26.0° and 4.6" of trail. The wheelbase numbers are nearly equal, however, the Tiger at 61.7" and the GS at 62.1". Because a longer swingarm assists the effectiveness of a bike’s rear suspension action, we thought we’d note their respective swingarm lengths as well. The Tiger’s swingarm is 25.25" from pivot to axle and GS measures 24.0". In practice, both bikes deliver good traction over rough ground without encountering the “tramping” action (rear axle hop) that often interferes with off-road drive when a too short swingarm or high unsprung weight resists keeping the tire in contact with the ground. Also, on the subject of geometry, our scales also noted a significant difference in weight distribution as well, the Tiger with 49.8% of the total on its front wheel (without the rider) compared to 47.5% for the GS. While the BMW’s figure is more typical of a dual-sport, and it is willing to change direction quickly in the dirt, it’s our judgement that both on the road and in the dirt, the Tiger gives a more planted front end feel, a better sense of front end traction and exhibits better straight-line stability. A full range of accessories are offered and available now, ranging from engine guards ($199.99), a bash plate ($199.99), a tank bag ($139.99), saddlebags ($799.99), top trunk ($399.99) and mount ($149.99), halogen fog lights ($329.99), headlight shield ($79.95), a centerstand ($219.99), a gel seat ($149.99), heated grips ($229.99), a windshield rake adjuster ($59.99) and more. Brakes, Wheels & Tires—Tiger 1st, GS 2nd Braking is the other category where the Tiger displayed a clear advantage over the GS. By all appearances, the equipment is top quality on both; Brembo components on the BMW, and Nissin on the Triumph, so you’d imagine equal performance. Although ABS is an option on both machines, most BMWs you’ll find in dealers’ showrooms are equipped with ABS and stripped down models are rare if not unobtainable. We made sure our Tiger was equipped with ABS for comparison purposes, but we wouldn’t be surprised if the majority sold are not equipped with ABS. The GS’ ABS can easily be deactivated in two seconds via a convenient button located on the left switchgear housing. Likewise, the Triumph’s ABS can also be deactivated by toggling through the various features on its multi-function LCD instrument panel, and while it’s easy enough to do, it takes much longer and can be a hassle when stopping and restarting the XC frequently, as one might when engaged in off-road exploration. Since both the Triumph and the BMW automatically default back into ABS mode whenever the ignition key is turned off, those wanting to keep the ABS turned off on the XC will quickly learn to leave its key in the “on” position when dismounting and remounting (leaving the headlight burning, draining the battery). Surprisingly, both bikes recorded virtually identical stopping performances during our braking drills in both ABS and nonABS distances—although the numbers don’t tell the whole story. In ABS mode, the BMW required 127.2' to stop from 60 mph, and the Triumph 128.4'. Without ABS, the Triumph turned the tables, stopping in just 117.3' to the BMW’s 118.1'. Call it even, but the superority of the XC’s dual 308mm floating rotors with Nissin two-piston calipers manifested itself in the form of a smoother, more linear feel at the lever, matched by a similar feel from its rear 215mm rotor and single-piston caliper. Despite its Adventureclass leanings, the XC’s brakes offer sportbike-style performance but with less initial bite, although MCN tester Danny Coe reported that they gained a little more bite once they heated up a bit. In either case, initiating smooth, consistent stopping action required little more than a single finger’s pressure on the front brake lever. The only complaint was of a slight high-frequency vibration in the Tiger’s front brakes during ABS activation. The BMW’s brakes drew mixed reviews from our testers. The GS is equipped with dual 300mm floating front rotors clamped by Brembo’s generally excellent four-piston calipers, and a 265mm rotor with a single-piston caliper out back. While the hard data suggests that they perform similarly to the Triumph’s, the reality is that the BMW’s brakes aren’t as user-friendly. Initial bite is strong, but the GS lacks the immediate response and linear feel of the XC when the front brake lever is squeezed, and the rear brake only adds to the sensation, thanks to its rangy pedal travel. Because of this, some testers found the rear brake tricky to modulate without inadvertently locking the rear wheel. The disparity was less clear-cut off-road, however, as one tester actually preferred the GS’ brakes to the XC’s when the ABS on both was deactivated, while another felt that the XC’s brakes were more effective in the dirt than the GS’ brakes when both were in ABS mode. Overall, though, the Triumph’s more sensitive feel trumps the BMW’s strong-but-delayed bite in most conditions. Both machines sport premium rubber on 21" front and 19" spoked rear wheels befitting their adventurous intentions. The Triumph rides on Bridgestone Battlewings, a 90/90-21 front and 150/70ZR17 rear, and the BMW wears identically sized Pirelli Scorpion Trials. The only noteworthy difference is that the Triumph’s front rim is slightly wider than the BMW’s, measuring 2.50" x 21" whereas the GS uses a 2.15" x 21" commonly found on the front of modern 250cc-450cc dirtbikes. That may sound like a slight difference, but the Tiger’s wider front hoop certainly contributes to the stable, planted feel of its front end. Of course, as you can see in our photos, we opted for more hard-core dual-sport tires for the majority of our testing, as we weren’t confident that we’d be able to fully experience either bike’s off-road capabilities with stock tires. With their aggressive off-road oriented tread pattern, Continental’s TKC 80s were more than up to the task (see Sidebar, page 17). Ergonomics—Tiger 1st, GS 2nd With the luxury of time to study the assets and liabilities of the F800GS, Triumph engineers were able to tweak the Tiger’s ergonomics for maximum comfort, giving it the nod in the category. For starters, the Tiger comes standard with a two-position seat, allowing it to be tailored to a wider range of rider inseams. The GS is available with two different seat heights at the time of purchase, but the buyer must decide on one seat and stick with it— or purchase another seat. Set in the lower position, our Tiger’s seat height was a comfortable 33.5", while the GS checked in at a taller 34.25" with its low seat. Tilting the ergo category even 80.10 hp 74.21 hp • • 50.67 lb.-ft. • • 48.51 lb.-ft. Comparative Dyno Chart—The Tiger in blue and the GS in red Visit us at WWW.MCNEWS.COM ● AUGUST 2011 15 Model Comparison more in the Triumph’s favor, the Tiger’s seat offers a flatter dish and more rounded contours than the BMW’s, which has a smaller main saddle area and sharp edges that can become uncomfortable on longer rides. Adding to its adjustability, the XC’s handlebar clamps feature a 9mm offset, so they can be installed in two different positions. Our test unit featured the handlebars in the rearward position, but flipping the clamps to the forward position would net an additional 18mm of cockpit room to better accommodate a larger rider’s arms and torso—a nice touch. Wind protection is another area where the Triumph scores. Neither machine features an adjustable screen, making height, width and positioning all the more important. The XC’s screen is slightly taller, wider and more upright than the GS’, making it more efficient at directing air away from the rider. Not that the GS’ screen is unnecessarily turbulent or inadequate, but the Triumph’s screen offers a noticeably cleaner windlblast. The BMW almost makes up all of the Triumph’s advantages in the dirt, however. Its wide handlebar features an ideal bend for off-road riding, and its cockpit layout is much more conducive to standing up, which can be a real benefit over rough terrain since it allows the rider to absorb some of the bumps with his or her legs. The Triumph favors a seated position off-road. When the rider stands up on the pegs, the Triumph’s handlebars are situated too low in the ergonomic triangle, limiting upper body freedom when standing. Although its handlebars are graduated, so they could be rotated forward to improve the rider’s body position when standing, the tradeoff is that the bars would likely be angled too far forward for smaller riders in the seated position even if the handlebar clamps were offset to the rear. The bars also have a narrow feel that hampers leverage, while the XC’s gastank imparts a wide feel through the middle when trying to shift your weight forward while standing. Riding Impression—Tie Our test schedule included a glorious day on the routes that run over scenic Palomar Mountain, home of the famous Palomar Mountain Observatory, near San Diego, California. Our ride included two-lane highway to and from our home base at Lake Henshaw, rippled pavement on the mountainous Palomar Divide Road, and various fire roads on the mountain itself—just the place for a comparison of these two Middleweight Adventure machines. With temperatures in the low 70s F and not a breath of wind, conditions were ideal, and that made it all the more difficult to find fault with either bike. Of the two, the Tiger 800XC is clearly the more street-oriented. Its lightning quick throttle response and 16 AUGUST 2011 ● MOTORCYCLE CONSUMER NEWS willingness to rev quickly make it an absolute joy on twisty pavement. And, with ample torque to fire out of slower corners and plenty of top-end performance, it may just be our new favorite Triumph engine—although it seems like we say that every time a new Hinckley model breaks cover. The BMW possesses its own engine character. Its power delivery is more abrupt, and its vibration level becomes unsatisfactory about the time its tachometer needle touches 5000 rpm. In the dirt, though, the BMW’s slowerrevving nature is welcome, as it can be revved to good effect without fear of excessive or uncontrollable wheelspin, something the Triumph simply can’t do. The XC is much more manageable when the rider keeps the revs low, rides it in a taller gear and maintains a conservative pace. This will usually keep its excellent-feeling suspension in the sweet spot, leaving the rider free to enjoy the scenery. BMW describes the GS as 60% dirt and 40% street, and we’d have to agree. The GS has a light, rugged and racy feel in the dirt, and equipped with good dual-sport or off-road tires, we have no doubt that it would be capable of tackling harsh desert terrain. Instruments & Controls—Tiger 1st, GS 2nd Despite the aforementioned complication associated with disabling its ABS, the Triumph Tiger 800XC’s instrumentation offers excellent functionality and is much easier to decipher than the BMW F800GS’ dash. The Tiger’s speedometer readout is digital, making it very easy to read how fast you’re going on or off the road. The BMW F800GS features a 150 mph analog speedometer with very small numbers that make it difficult to read no matter where you are. Offset to the right of the instrument panel, the Triumph’s large-faced tachometer is also much easier to read than the smaller tachometer crammed just below the speedometer on the BMW, and the Triumph’s features large buttons on the left side of the panel that make it easier to toggle through its various trip functions, all of them standard unlike the BMW, whose base price doesn’t even include a gas gauge (our test unit came optioned). Both machines offer adjusters on their front brake levers, but the Triumph’s more common rotary-style adjuster can easily be changed on the fly. Located on the backside of the lever close to the pivot, the BMW’s adjuster is small and hard to rotate when motoring. The GS also has an adjuster on its clutch lever. The XC doesn’t. Attention To Detail—Tiger 1st, GS 2nd Both of these machines offer many of the same amenities that are compulsory in the Adventure category, such as effective windscreens, serrated footpegs with removable rubber inserts and convenient auxiliary power ports located next to their ignition switches to facilitate the use of a GPS or other accessories. But there are subtle differences that favor the Triumph in this category: The Tiger’s more powerful 645W alternator allows more options than the BMW’s 400W unit, and in addition to its nicely designed two-position saddle and more readable instrumentation, the XC comes standard with high-impact poly resin handguards and a rear rack. The Triumph also looks more like a dirtbike than the BMW, thanks to its black tank and radiator guards, which we can confirm are plenty tough, after a tipover in the dirt when the XC stalled just as we were trying to get underway. Had a similar incident happened to the white painted radiator covers on the GS, the end result would have been far more unsightly and certainly more expensive to repair. Of course, styling details are mostly subjective, but we still favor the Tiger 800 XC’s symmetrical dual headlights over the F800GS’ asymmetrical headlight design. BMW claims that the shapes are a straightforward reflection of the lights separate functions, but whether or not that’s significant, it doesn’t mean the GS’ odd-shaped headlights are any easier to get used to, even now. Value—Tiger 1st, GS 2nd Value is determined by measuring a motorcycle’s performance relative to its MSRP and comparing the result with other bikes in its class. As Triumphs have a reputation for delivering extremely high performance at an affordable MSRP while BMWs are wellknown for premium pricing, we expected the Tiger 800XC to win the Value category hands down, but its advantage is smaller CONTINENTAL TKC 80 TIRES Picking the appropriate tire for an Adventure bike is always a tricky proposition. The weight of the bike and the intended terrain are critical. Don’t bother with a knobby if you’re not planning to use the tire off-road at least half the time, and if you want to ride surfaces rougher than a smooth dirt road, you don’t want anything less than knobs to give you the grip you need. Previous experience convinced us the Continental TKC 80 Twinduro would be right for these heavy dual-sports. Standard equipment on the big BMW R1200GS Adventure and the KTM 690 Enduro R, the TKC 80 tires have proven very popular. Designed in collaboration with Richard Schalber, German offroad ace and five-time Enduro World Champion, the TKC 80s were designed specifically for the big BMW GS machines. With than we anticipated. The Tiger 800XC’s $10,999 base MSRP is only $456 less expensive than the $11,455 base MSRP for the F800GS, but adding ABS jacks up the price of both machines. As tested, our Tiger retails for $11,799, while our optioned (Standard Package) BMW retails for $12,900, for a difference of $1101. That’s not insignificant, although the GS’ Standard Package price includes BMW’s excellent heated grips. Adding heated grips to the Tiger will set you back an additional $299.99, narrowing the price gap between the two machines to just over $800. Then again, the base Triumph already includes handguards and a rear rack, and the BMW doesn’t, even at the higher price. Overall—Tiger 1st, GS 2nd Choosing a winner here is difficult. Prospective adventure riders considering either of these two machines are going to have to stare into the mirror and decide what kind of riders they are to determine which of these two machines will best suit them. If you enjoy marathon rides on long—and preferably twisty— stretches of open road, and you want to throw in more than a few dirt fireroads for fun, then the Triumph Tiger 800XC is a clear winner. For others, whose riding style emphasizes prowling the untamed wilderness, the BMW F800GS may be worth a good, hard look. Even so, at the end of the day there’s no denying that the Tiger 800XC is the more polished machine here. In their first try, Triumph engineers went to school on the class leader, did their homework and produced a bike that offers the better compromise. Bravo, Triumph! a widely spaced tread blocks and slightly shorter than average knobs, they handle the weight without squirming. On the street, the TKC 80’s handling and cornering abilities are surprisingly good for such an aggressive design and the ride quality is remarkable. In the dirt, the tires have excellent grip and directional stability and plenty of traction on loose and rocky surfaces. Sand is never much fun on a heavy dual-sport, but the TKC 80s are also good on the soft stuff. Developed particularly for softer terrain, the rubber compound is on the harder side, so it tends to last fairly well in combination street/dirt use, and 4000-5000 miles would be a fair estimate of their tread life. If making a big street-biased dual-sport into a more capable offroader is your goal, we think the Continental TKC 80 Twinduro tires are an excellent choice. Visit us at WWW.MCNEWS.COM ● AUGUST 2011 17 Model Comparison Left: The Tiger holds more fuel but gets less mpg for approximately equal range with the GS. We really like its ergonomics on the road or seated offroad, but the handlebar is too low for a good standing position, and some complained that the rear of the tank interfered with body positioning. New bars would be an easy fix. Right: A two-position rider’s seat is standard (shown here in the lower setting). All testers agreed the Tiger’s saddle was superior to the BMW’s. Note, too, that the Tiger includes a rear rack as standard, an option on the GS. Like the GS, rubber pads on the rider’s footpegs are removeable for a cleated surface off-road. Above: The Tiger’s digital speedo is much easier to read at a glance than the GS’ 150 mph analog clock. Fully featured with a gas gauge at no extra charge (unlike the BMW), our only gripe was the hassle of turning off the Tiger’s ABS with a lot of info scrolling each time we started the engine when riding off-road. Left: Triumph’s very compact triple delivers smooth power from much lower rpm and its Keihin fuel injection provides superior driveability than the F800GS twin. The bottom placement of the catalytic convertor reduces ground clearance, which could be a worry over very rocky terrain. Right: The Triumph’s brakes are decisively better than the BMW’s, with much better feel and no delay between application and slowing. The Tiger’s Showa suspension, while giving a fraction less travel, more than makes up for the deficit with quality, offering better feel and compliance. Like the BMW, the XC’s forks are nonadjustable. TESTERS’ LOG Triumph knew exactly what it had to beat, and the two bikes are so close in character, despite their different engine configurations, that the contest was obviously going to be a tough call. Acceleration, braking and top speed were almost identical, yet the BMW, with less top end power, had the edge—a matter of gearing and 13.5 lbs. less weight to haul, apparently. Over the road, I was quicker on the Triumph, and found myself charging deeper into turns as I had such good control over the brakes, while the machine’s slightly lower CofG gave it sportier handling. In the dirt, everything was magnified. I could clearly sense that the Tiger carried 18 lbs. more weight on its front wheel, and that made it friendlier to my riding style—smooth and flowing. The suspension helped its fine feel, too, and although the BMW’s didin’t feel bad by any means, the Tiger’s was just a little better. Lastly, its driveability was a big plus for the Tiger. I learned to gear up and let the engine torque its way forward, strong and controllable. A more aggressive rider might not agree, but the Tiger is my favorite. —Dave Searle 18 AUGUST 2011 ● MOTORCYCLE CONSUMER NEWS With one memorable exception, I’ve never met a Hinckley Triumph without some redeeming quality, and although the Tiger 800XC isn’t my favorite of the two motorcycles here, it is certainly worthy of praise. I’ll even concede that it’s the better streetbike of the two. On the street, I dig the seamless power of its stroker triple, and its supple Showa suspension boasts spoton damping rates. That suspension quality is virtuous in the dirt, too, especially over harsh low-speed hits. The Triumph’s seat is also more comfortable than the BMW’s. The Triumph comes up short for me in the dirt, though. Compared to the BMW, it feels wide, heavy and resistant to quick direction changes at speed, its engine isn’t nearly as tractable for the type of off-road action I enjoy, and it lacks suspension travel. Its low, narrow handlebar also doesn’t afford enough leverage in rough or loose terrain. Changing to an off-road handlebar bend would help, but the Tiger 800XC still doesn’t mix nearly enough dirtworthiness into its recipe for my taste. —Scott Rousseau 2011Triumph Tiger 800XC SPECIFICATIONS AND PERFORMANCE DATA ENGINE PERFORMANCE Type: ..liquid-cooled four-stroke triple Valvetrain: ..........

The lower panels were once black, but have now been made body-colored, for a stronger resemblance to the 799cc F650GS, but which will make off-road tipovers more noticeable. The strong twin-cylinder motor remains unchanged, still with abrupt throttle response at low rpm, which hurts off-road use unless the rider is very experienced and aggressive. On the road, this flaw is hard to notice. Top: The F800GS’ instruments are harder to read at a glance than the Tiger’s and you must pay extra to get a gas gauge. However, the GS’ ABS is easier to disengage for dirt riding. The windshield is also lower than the Triumph’s, giving less protection. The GS’ handlebar is much higher and better for a standing position, however—a big advantage off-road. Bottom: BMW has finally made the decision to convert its handlebar switches to the conventional type. However, existing models like the F800GS may have to wait their turn. Its turnsignals still use the left and right side signal buttons with rightside cancel and the odd lift instead of push horn button. We won’t miss them when they are all gone. Above: All testers agreed the GS seat is less comfortable than the Tiger’s. Sharp outer edges cut into the thighs and its height is not adjustable—the rider can choose high or low seats at purchase time. Right: The GS’ suspension lost to the Tiger’s for quality, if not quantity; losing out for both its feel and compliance. BMW’s brakes also come up short to the Tiger’s with an odd delay in engagement and an overly sensitive rear disc. TESTERS’ LOG I had an epic off-road ride at the F800GS’ Moab intro, so I was skeptical that Triumph had built a better 800cc dual-sport. On the street, the two seemed almost perfectly matched, but once in the dirt, the subtlties of their weight distribution, steering geometry and power delivery set them distinctly apart. The BMW sounds great, and if it were up to my ears to decide the contest, the GS would win. But it still has very sudden throttle response from plonking rpm, making me work harder, constantly feathering the clutch, to be smooth at low speeds. Also, the bike feels taller and heavier, even though it’s lighter—due to a taller center of gravity. It also feels less steady on soft ground, hunting from side-toside, where the Tiger is steady (riding on the same tires). But where I noticed the greatest difference was on the brakes, the GS with a tentative feel and what seems like a second of delay between my squeeze and any slowing—sapping confidence. And that’s probably not something that can be fixed, but a characteristic of the ABS. I was surprised, but ultimately convinced, the GS comes in second for me. —Dave Searle 20 AUGUST 2011 ● MOTORCYCLE CONSUMER NEWS The F800GS is still the king of the 800cc Adventure class in my book. What refinement details it concedes to the newer Triumph Tiger 800XC are more than offset by its exceptional off-road capabilities. During our dirt excursion over Mount Palomar, I found myself attempting to negotiate obstacles on the GS at a pace I wouldn’t even think about on the XC. The GS’ slower-revving parallel twin is more off-road friendly than the XC’s, allowing me to be aggressive on the throttle without fear of uncontrollable wheelspin, its brakes aren’t as sensitive as the XC’s in the dirt, and it offers more compression braking. Its suspension isn’t as refined as the Tiger’s, but has more travel front and rear. Also, the GS’ 10-lb. lighter weight might as well be 50 when it comes to the difference in handling character. Both bikes track straight and true, but the quicker-steering BMW is more willing to change lines than the Triumph is—a necessity in the oftenunpredictable off-road environment. Dirt worthiness is what makes an Adventure bike an Adventure bike. In my mind, the BMW F800GS is unquestionably the more adventurous bike here. —Scott Rousseau 2011 BMW F800GS SPECIFICATIONS AND PERFORMANCE DATA ENGINE PERFORMANCE Type: ........ liquid-cooled parallel twin Valvetrain: ....
