Kawasaki Z900 RS 2018

Kawasaki Z900 RS 2018

Its four-cylinder is silky smooth while delivering enough power to make you grin under your helmet. It is also very easy to move, which should make it a great commuter bike in everyday life and serve as an iconic fun bike at the weekend. The looks find the perfect straddle of classic design and modern details to form a coherent retro package that is also a worthy tribute to Kawasaki history. It's a great naked bike with a snazzy look.

Powerful and smooth engine

good looks

comfortable seating position

easy to ride

balanced handling. Not nervous and not ponderous

no shift assistant

heavier than other retro bikes in this class

seat a little too soft on long tours

no wind protection
