2012 BMW R 1200 GS and 1200 GS Adventure

Introducing the new BMW R 1200 GS and the new R 1200 GS Adventure, BMW Motorrad is opening up yet another chapter in the story of highly successful GS models which, for almost three decades, have been the epitome of the large capacity grand touring enduro. Moving on from the former generation of the R 1200 GS and R 1200 GS Adventure, which already offered supreme power and performance as well as a very
broad range of practical riding qualities for long tours combined with supreme pleasure on winding country and mountain roads, BMW Motorrad is now enhancing this standard, as impressive as it already is, to an even higher level.

In its construction principle and fundamental layout, the new fl at-twin power unit is the same as the DOHC engine on the BMW HP2 Sport. But marking the new generation, the engine has been carefully updated and optimised for the R 1200 GS and the R 1200 GS Adventure, tailored to the specifi c requirements of a grand touring enduro. With the 1,170-cc Boxer engine on the former models already ensuring supreme power under all conditions and in all situations, the new R 1200 GS and R 1200 GS Adventure have even more to offer in virtually every respect:
Delivering maximum output of 110 hp, reaching top engine speed up by 500 to 8,500 rpm, and with an even broader range of engine speed, the new GS models are even more dynamic, powerful and muscular in terms of both torque and acceleration throughout the entire speed range, thus setting the standard once again for the grand touring enduro also in terms of riding dynamics.

Designed and built from the start for higher engine speed, the new fl at-twin power unit in the R 1200 GS and R 1200 GS Adventure, like the power unit featured in the BMW HP2 Sport, comes with two overhead, chain-driven camshafts (DOHC) per cylinder. The valves are operated by very light rocker arms able to cope with even very high engine speeds through their low weight alone. Radial arrangement of the four valves is ensured by the very compact combustion chambers. Like on the former models, the fuel/air mixture is ignited
by two spark plugs (HP2 Sport: one spark plug), and the compression ratio of 12.0:1 is also the same as before.

Moving on to the exhaust system, the two manifolds are the same as before in their design, length and diameter, while a modifi ed interference pipe caters for the change in vibration conditions in the exhaust system. Featuring an exhaust fl ap controlled by an electric motor as well as opening and closing cables, both the new BMW R 1200 GS and the new R 1200 GS Adventure provide a particularly throaty boxer sound naturally in full compliance with legal standards. And to reduce ram pressure and improve the sound of the engine even further, the rear silencer remaining the same in design as on the former models comes with a completely new interior structure.

The new R 1200 GS and R 1200 GS Adventure also benefi t from optimised shift kinematics with an optimised power/travel curve for precise gearshift and clear feedback at all times. The maintenance-free drive shaft to the rear wheel also remains unchanged, relieving the rider of annoying and time-consuming maintenance requirements particularly on long tours.
