BMW S 1000 RR 2021

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 2023

Kawasaki Z900 2023

The Kawasaki Z900 may not be up to scratch when it comes to modern, lean angle-dependent electronic features, but it's relatively cheap and you shouldn't underestimate the fan base of the good old inline four - the Z900 is one of the cheapest ways to own such a great engine with just under a litre of displacement in a sporty naked bike! The higher weight is noticeable, but not massively annoying, because the handling and stability are quite alright. In terms of "outdated" electronics, the most annoying thing is the missing shift assistant, which is not even available as an option. Overall, however, the Z900 is a great naked bike with a great price-performance ratio.

Light and natural handling with high stability

silky engine with full pull from low revs

high chassis transparency, great feedback

seating position with feel-good factor

absolutely fair price.

Relatively cumbersome operation of the menu

no slope-dependent assistance systems

high weight
