For more than 25 years, BMW Motorrad has used 4-valve technology, combined with electronic fuel injection and closed-loop catalytic converter technology in order to achieve the best possible power and torque delivery, efficiency and environmental compatibility.
Further advanced boxer engine with BMW ShiftCam Technology for an additional increase in power across the entire engine speed range, reduced emission and fuel consumption levels, optimised running smoothness and refinement.

With the extensively further advanced boxer engine, the new R 1250 GS and R 1250 RT not only achieve a whole new level of power and torque.
It was also possible to significantly optimise refinement and running smoothness – especially within the lower engine speed range. What is more, the new engine offers improved emission and fuel consumption levels as well as a particularly satisfying sound.
For this purpose, BMW ShiftCam Technology has been used for the first time in the serial production of BMW Motorrad engines: this enables variation of the valve timings and valve stroke on the intake side.
In addition, the intake camshafts are designed for asynchronous opening of the two intake valves, resulting in enhanced swirl of the fresh, incoming mixture and therefore more effective combustion.

Other technical changes to the engine relate to the camshaft drive – now taken care of by a toothed chain (previously a roller chain) – an optimised oil supply, twin-jet injection valves and a new exhaust system.
Overview of the highlights of the new BMW R 1250 GS and R 1250 RT include increased output and torque: 136hp at 7, 750 rpm and 143Nm at 6 250 rpm (previously: 125 hp at 7, 750 rpm and 125Nm at 6, 500 rpm).
Capacity increased to 1, 254 cc (previously: 1, 170 cc). New exhaust system for optimum performance characteristics. New additional front spoiler on the R 1250 RT. Two riding modes, ASC and Hill Start Control as standard.
