Kawasaki Z650 2021

Even in 2021, the Kawasaki Z 650 stands for easy riding with great looks and good equipment. Both seat height and engine are very accessible and will give both experienced riders and newcomers a lot of pleasure. If you are looking for an honest naked bike without any big surprises, this is the bike for you.

Kawasaki Vulcan S 2015

Kawasaki Vulcan S 2015

The Vulcan S is reinvigorating the "small" mid-size cruiser scene - not only because of its unique design, but also because it is so easy to ride and is aimed at beginners. The low seat height and the narrow saddle help the rider to stand securely on the ground, while the low centre of gravity also makes for easy and safe handling. The engine also fits in well with the uncomplicated appearance, can be revved up decently from 2000 rpm and only stops at around 10,000 rpm - something that has never been seen before in a cruiser. The "Ergo-Fit" system, which varies the seat height, the rider's distance from the handlebars and the footrests, costs extra but also allows the Vulcan S owner generous customisation options.
