The R1200GS is powered by the biggest engine in any dualsport bike, now with the high-performance cylinder heads proven in World Endurance Championship
roadracing by the BMW HP2 Sport. Featuring dual overhead camshafts per side and
radial valves, they increase the power output, torque, and usable rev range. A six-speed close-ratio
gearbox features all helical gears and a low-friction shifter mechanism for smooth shifts. The exhaust system features an
electronically-controlled bypass valve for quiet stealth at small throttle openings and a throaty roar when riding hard.
The R1200GS achieves a remarkably low weight through precise engineering and the use of high-strength materials. The smooth-running Boxer engine, as always, has a very low centre of gravity.
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 has been enhanced in many ways since it was introduced to worldwide acclaim in 2004. 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 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 option is the unique 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.
