Superbike engine perfected for a hyper roadster: the four-cylinder engine from the RR with BMW ShiftCam technology catapults you from 0 to 100 kmph in 3.2 seconds. With a maximum engine speed of 14,600 rpm, the M R is clearly our most powerful roadster. From 10,000 rpm, you can consequently feel more torque and acceleration. In terms of gear ratio, the M R has more to offer compared with the RR: 47 instead of 46 teeth in the secondary gear ratio and a shorter gear ratio in 4th, 5th and 6th gear – for performance-oriented riding along country roads. Shift assistant Pro enables fast upshifts and downshifts. The bike’s rich sound originating from the titanium rear silencer impressively emphasizes this.
