Kawasaki Ninja ZX-10R 2021

Kawasaki offers a mature overall package with the Ninja ZX-10R in the 2021 model year, which with the new front end also really looks like 2021. The bike offers surprisingly good space for the rider and you feel comfortable in the saddle. The rev-happy engine leaves nothing to be desired - except perhaps more discipline in the part-load range. To make the project a success, Kawasaki relies on high-quality ingredients: Showa suspension, Öhlins steering dampers, Brembo brakes with 330 discs and high-quality electronics. Thanks to the good electronics and the superior engine, the Ninja ZX-10R even cuts quite a figure on country roads - as long as you are willing to suffer a little in terms of seating position due to the concept.
