Kawasaki Z900 RS 2022

The Z900 RS enjoys a large fan base and in 2022 it once again proves why it is so popular. The powerful engine scores with pulling power and a wonderful sound that is not too obtrusive. The handling feels natural and presents no challenges. Only a quickshifter would suit the bike - even if that doesn't quite fit the retro idea.
