The not-so-ordinary RllOOGS ha s. come a long way since the first on/offroad GS model was introduced nea rly 15 years ago - the RSOGS. Since that time, the GS line has seen many changes and innovations, but none as rad ical as those featured on the all-new 1995-yearmodel RllOOGS. It was only a matter of time before BMW's "new generation" Boxer motor, that was first introduced early last year in the brand new R1100RS, found its way into the GS model. Despite minor internal changes to give the GS better torque and midrange performance , making it better-suited for those occasional off-road excursions, the air / oilcooled, horizontally opposed, two-cylinder, ei ght-v alve engine is id en tica l to that of the all-street RllOORS Beemer. The motor is sign ificantly smoother a nd more powerful th an the last GS model we tested a while back with the "old" Boxer motor. The new GS pulls much harder off the bottom and through midrange than before, an d, with a lot less vibration, though vibration is still somewhat of a nuisance. We spent a: couple of days exploring the twisty roads of Northern California on the GS and were perh ap s most impressed by the the engine's superwi de spread of power. Because of the .Beemer's extremely hea vy engine braking, and the notchy-feeling and a hardto-find gear shift lever (a little too low for our liking), clicking up and down through the gears wasn't exac tl y a pleasant experience, but it really didn't matter all that much. Instead, you can simply leave the GS in one gear, usu ally third gear, and ignore the shifter all together. Even in the tightest of turns, you can leave the bike in third, roll on the throttle and the GS will pull you nicely out of the comers. And you won't feel the need to click up a nother cog until the speedometer needle nears 60 mph. (Speaking of the sp eed ome te r, ours wa s a little overly zealou s in its readings. The odometer on our test bike gained approximately l/lOth of a mile per every two miles traveled). If you start riding the GS aggressivelyon the pavement, shifting becom es a very conscious procedure, especially while downshifting. You have to be cautious when letting out the clutch leve r after dropping down a gear; there is so much engine braking that if you're not careful, the back tire will slide out if the bike isn't perfectly perpendicular to the road. Accomplishing a smooth, clean shift is an art form with the GS. However, the dry, single-plate clutch works extremely well and has a super-smooth feel. Up front, the GS also uses the same Telelever front suspension sy stem as that of the RS, bu t there are some significant differences. For obvious reasons, the GS has more w heel trave l, and , unlike the RS where the rider can easily feel the handlebars ro tate in his/her hands as the Telelever front suspension compresses and rebounds, this feeling is virtually eliminated on the GS, despite the fact that BMW engineers say the handlebars still move slightly. In the back, the GS still uses BMW's Paralever system, which incorpora tes a full-floating rear ax le, double-jointed drive shaft and a stabilizing torque arm to virtually eliminate the torque reaction of the shaft drive. But, like the new RS model, the shock on the GS has been relocated from the right side to a mor e central position. All in all, we were quite impressed with the overall suspension package. Many of the tight, switchback roads we traveled on were surprisingly rough, with a lot of dips and enough small holes in the pavement to keep yo u on your toes . But the GS ha d no problems handling whatever the roads dished out, and in these conditions was a lot more desirable than any sport bike. The GS comers surprisingly well and is simply a blast to ride on mountain or canyon roads - it would make the K1100RSproud. Looking closely at the GS, you 'll start to think that som ething is missing, and you are right - the GS has no real frame to speak of since the engine acts as the bike's stressed member. The on ly section that resembles a tra ditional fram e is the rear sub-frame section that supports the sea t, the passenger footpeg assembly, bod ywork, rear fender and optional luggage bags. BMW's ABS II system also found its way onto the GS - as an option - but has one very significant feature not offered on the RS model. The GS's ABS can be shut down w ith a push of a bu tt o n . There are times when ABS isn't necessarily advantageous, like when logging in some serious off-road riding. By holding down the ABS confirmation bu tton on the small inst rumen t panel d uring engine start-up, the rider can deactivate the system until the engine is shu t off and restarted. We would deactivate the ABS whenever we spent any significan t tim e on the dirt. Even if left on. the ABS wor ked well on dirt roads , and despite spinning the rea r tire coming o u t of s lip pery turns many tim es on the GS, the ABS ne ver switched into "fault mod e." But according to BMW reps.It very well can. A pair of four-p iston Brembo calipers squeeze two 12.D-inch d iscs at the front, while a sliding two-piston caliper and 10.S-inch disc operate at the rear. Both brakes are stro ng and have good feel, but the front brake feels a tad on .th e mushy side. Wheel sizes have also been changed to complement the new chassis. Our test bike came fitted with a 150/7D-H17 Metzeler rear tire, wrapped aroun d a superwide 4.00 x 17-inch rim wit h cross-spoke lacing . The front no w features a wider, smaller-di ameter 1l0/ SD-H19 Metzeler tire and a 2.5 x 19-inch rim. There are many key design elements that make the GS well-su ited for lon g hauls in the saddle, most notably the large, 6.6-gall on gas ta nk, w h ich includes one gallon of reserve. The tank itself is constructed of a li ghtw eigh t plastic-like plyam id e mate ria l, as opposed to the more trad itional aluminum or steel variety . According to the Beemer's od ometer, th e lo w-on-fu el warning light would ill umi na te anywhere between the 260 and 270 mark. Figure you have another 40-50 miles left in the tank, and you have a bike tha t pushes the 300-mile envelope. That's pretty far when you thi n k about it . There is no on/off/reser ve switch on theGS. Despite the fact that the fra m emounted fairing/ windscreen is rat her small, it does a surprisingly good job of protecting the rider. There is little buffeting in the cockpit even at speeds up to SO mil es an hou r. But d on ' t both er tucking in behind the clear windscreen the plastic dis torts the rider' s view horribly, almost to the point of making you sick to your stomach. The angle can be shifted as much,as 13 degrees to adjust the airflo w o ve r the rider, yet we couldn't tell much of a d ifferenc e between the two settings . The rider's portion of the two -piece seat offers two posit ions, giving se a t heights of 33.9 or 33.1 inches - we preferred the highest setting. The passenger seat can be removed entirely to provid e additional space for a strap-on bag or handgrips, a variety of saddlebags and other luggage. liners, a tan kbag, soft foam grips, hand Our GS test bike ca me with the protectors (w hich, in our op inion, sho uld be standard equipmen t), an an tioptiona l locking saddlebags, which can be eas ily removed and reatta ched.
