Pros and Cons in comparison

BMW F 900 XR 2021

A motorbike in this performance class probably cannot be more accessible. The XR wobbles playfully through the radii and immediately inspires confidence in the saddle. Even long tours are easy and you are always relaxed when getting out of the saddle. However, the sporty look of the BMW also awakens desires for a little thrill. However, the power unit cannot quite fulfil these desires. The engine, transmission and quickshifter are a little too tame overall and could do with a little more sportiness.
