QJ Motor SRK 921 RR 2026

QJ Motor SRK 921 RR 2026

All in all, the QJ Motor SRK 921 RR is a serious alternative in the mid-range supersport segment. It combines sophisticated hardware with a stable chassis design and a linear, powerful engine on a par with the competition. Minor weaknesses such as constant ride judder or the somewhat impractical operating logic for the riding modes only slightly spoil the picture, especially as QJ is known as a manufacturer for making improvements quickly. Anyone looking for a bike with substance, confidence and an emotional sound will find a coherent overall package that is much closer to the established top dogs than you would expect.

Yamaha R7 2021

All in all, the R7 is a very good beginner's track bike that prepared me for track riding in a safe, pleasant and in no way strenuous way and accompanied me along the way. The pleasant yet track-ready ergonomics, the light weight, the fantastic tyres, brakes and suspension components and the torquey engine at low and medium revs allowed me to correct mistakes that most novice track riders make, and all without bringing me down, scaring me, scaring me or even making me throw in the towel.
