The R1200GS achieves a remarkably low weight
through precise engineering and the use of high-strength materials. The 1200cc
counter-balanced engine smoothly delivers 105 hp; the Boxer engine, as always, has a very low
cente of gravity. The exhaust system is quiet yet has
a throaty sound.
Torque from this, the biggest engine in any enduro, is prodigious. A new six-speed close-ratio gearbox features all helical gears and a new low-friction shifter mechanism for smooth shifts.
The Telelever front suspension is light and strong. The rear Paralever is totally free of any driveshaft jacking effect. The standard rear spring strut has travel-dependent damping for a smooth ride over small ripples and good control over big bumps.
BMW's fabulous EVO brakes with optional Integral ABS Generation II are fitted. On
the GS, the ABS may be switched off (if desired) for off-road use. The Semi Integral
system automatically provides load-sensitive rear braking when the hand lever is used;
the foot brake operates the rear brake only.
The R1200GS is enhanced in many ways for 2008. Power has been increased and the engine has a wider powerband. Transmission changes enhance traction, acceleration and gear shifting. Ergonomics are optimized with a new seat, new hand protectors, and new double-butted aluminum handlebars. The handlebars can now be installed in a position ideal for riding offroad while standing. Detail changes include a higher-output charging system and new fuel level sensor system.
A really useful new option is the Enduro ESA. ESA Electronic Suspension Adjustment provides on-the-fly setting of shock absorber modes (Normal, Sport or Comfort settings of compression and rebound damping on both front and rear shocks. When stopped, the rider can adjust for load (solo, with luggage, or two-up) with just the push of a button. The Enduro ESA adds two modes for offroad, with spring adjustment at both front and rear. The more severe setting also increases the ride height of the bike by about 2 cm.
Riders with shorter inseams are also accommodated with the new lowered chassis option. The seat height is brought down to 790 mm (31.1 in). Combined with the light weight of the GS and narrowness in the fuel tank area, the lowered bike is especially easy to handle.
Optional Stability Control (available with ABS)
excessive wheelspin and consequent loss of stability. Tire pressure monitoring, also available, will warn
of a flat tire due to a puncture before the tire deflates to a dangerous level.
