Unleashed passion: we have once again transferred all the experience from the race track to the high-performance BMW ShiftCam four-cylinder engine in the RR: 205 hp. The airbox from the M RR provides particularly good air supply and improved load changes. The cylinder heads with new channel geometry and reinforced bearing brackets also stem from the M RR. We have also optimized the standard Shift Assistant Pro. It now also permits gearshifts with overrun upshifts and overrun downshifts and provides improved load change damping – for gearshifting precision. And even the rear sprocket has more teeth now: just like in the M RR, it now has 46 teeth instead of 45 – for power down the straight.
