M RR four-cylinder engine-based BMW bikes on the RR engine for racing sport. Even more peak power, higher torque in the medium range, and 500 rpm more maximum speed.
- 156 kW output at 14 500 rpm and thus 4 kW more than in the RR. The maximum torque of 113 Nm at 11 000 rpm.
- New 2-ring forged piston 12 g lighter, adapted combustion chamber and compression increased to 13.5. Besides, slimmer and lighter rocker arms.
- Fully machined intake bike ports with new duct geometry and BMW ShiftCam technology for varying the valve control time and valve lift.
- Titanium valves, on the exhaust side with new spring assembly, slimmer, and 6 % lighter rocker arms, and optimized camshafts.
- Very light, compact engine block with longer and 85 g lighter titanium connecting rods from Pankl for reduced friction power and less weight.
- anti-hopping clutch without self-reinforcing for optimum Launch Control.
- Optimized differentiated intake system with shorter intake funnels for optimized gas exchange at high rotational speeds.
- New, 3,657 g lighter exhaust system with exhaust manifold, front silencer, and rear silencer made of titanium.
- M winglets and high windscreen: Braking later and accelerating earlier and more stability when cornering thanks to the aerodynamic downforce without any reduction in maximum speed.
- “Rain”, “Road”, “Dynamic”, “Race” and “Race Pro1-3” riding modes and the latest generation of the Dynamic Traction Control (DTC) and DTC wheelie function with a 6-axle sensor box.
- Two adjustable characteristic throttle curves for optimum response characteristics. Engine brake with threefold adjustable engine drag torque in “Race Pro” mode.
- Shift assistant Pro for shifting gears up and down without clutch. Simple reversibility of the shift pattern for race track use.
