Pros and Cons in comparison

BMW S 1000 RR 2021

A real "all-rounder" superbike. The BMW knows how to play to its strengths both on the race track and on the country road. Thanks to variable camshaft control, the powerful engine is already convincing at the bottom end and accelerates harmoniously across the entire rev range, with plenty of power in every range. For the hobby pilot, the chassis certainly functions excellently in every situation, provides transparent feedback and offers many adjustment options. The seating position is sporty yet relatively comfortable. The electronics work very harmoniously without patronising the rider - TOP!

Very linear power delivery, which makes it particularly controllable. Wide rev range and pleasant control

thanks to ShiftCam, there is also plenty of pressure in the lower rev range

excellent DDC - precision and TOP performance

super electronics package

harmonious overall package both on the road and on the racetrack

In part, the bike seems almost a bit "characterless" compared to the Aprilia and Honda

In direct comparison, the bike lags a bit behind on the spec sheet

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
