BMW R 1250 R 2019

What could be better than getting even more power and torque in an already powerful naked bike! The predecessor, the R 1200 R, with its 125 hp and Newton metres of torque, could already be ridden very sportily, but the enlarged R 1250 R, now with 136 hp and a massive 143 Newton metres, pushes the boxer power to its current peak. The special thing about the R 1250 R, as with its predecessor, is that thanks to the extensive range of accessories it can also convince on tours. The new engine with ShiftCam valve control is not only more powerful but also more refined. The chassis and brakes are also convincing, and the seating position is pleasantly upright, allowing a wide range of riding styles, from sporty push-off to long-distance touring.
