BMW S 1000 R 2023

The seating position is sporty, but by no means uncomfortable, the brakes are powerful and the engine of the S 1000 R is at its best - perhaps even a little too homogeneous. There is also nothing to complain about on the riding side. Based on the pure performance data and the installed electronic features, the BMW probably has what it takes for the fastest lap time. And that on any kind of surface, because with the semi-active suspension you can eat up kilometre after kilometre on bad roads littered with potholes. Unfortunately, this feeling of superiority never really spilled over to the driver. Probably the downside of too much balance in all areas - at least in my Italophile eyes. The BMW lacked that certain something, the charisma, which is difficult to explain but arouses genuine emotions.
