Pros and Cons in comparison

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

Harley-Davidson Nightster 2022

Harley-Davidson Nightster 2022

Comfort on long rides, a lot of fun on winding roads and easy handling: I felt at home on the new Harley-Davidson Nightster right from the start. It's a bike that can be ridden fast around the bends or cruised in a relaxed way - with an engine that is powerful but not intimidating. On the modern Sportster version, I appreciate the presence of traction control, anti-hopping clutch and different riding modes. The Nightster gives me a real Harley feeling, just a little more unexcited compared to its predecessors. For my California trip, it was exactly the right choice.

easy handling

comfort on long distances

extensive equipment with riding modes, traction control, anti-hopping clutch and more

chic & modern Sportster look.

Relatively small fuel tank

Keyless system only for ignition, not for handlebar lock and fuel tank

Rear suspension not very comfortable on rough road surfaces
