Kawasaki Z900 2018

In the hotly contested naked bike segment, the Z900 plays right at the front. Above all, its engine is absolutely terrific, runs incredibly silky and offers rich power in all rev regions - as befits a Japanese four-cylinder. Its sporty, aggressive appearance matches this. It does without electronic bells and whistles, but still conveys a lot of confidence when chasing corners, braking and accelerating out of them. The low seat is especially beneficial for smaller riders, but taller riders might miss a flatter knee angle on long distances. The low weight and compactness make the Z900 particularly agile and easy to handle. A sporting cannon that is also extremely appealing in terms of price
