Kawasaki Z900 70kW 2018

Kawasaki Z900 70kW 2018

The Z900 is a top entry-level motorbike. Very smooth engine, great brakes and lots of adjustment options on the chassis and levers. The acceleration may be too good for speed junkies, but it's just right for learning. The lack of electronic gimmicks, riding modes and traction control doesn't bother either, but makes the Z900 a good bike to learn the basics of two-wheeled locomotion. A high-quality purist, a real motorbike, even with only 48 hp!

Smooth engine with punch at approx. 6000 rpm

Finely controllable brakes

Smooth running of the engine super for city traffic

Typical 4-cylinder shriek, but very restrained at low revs

Stable at motorway speeds

Good handling

Quite small for tall people

rather high weight of 210 kg

acceleration with 48 hp rather poor due to weight

Aprilia Tuono 660 2021

Aprilia Tuono 660 2021

The Tuono delivers on the bends what the name promises. The sporty naked bike rides precisely and you enjoy the sporty corner chase. At the exit of the bend, however, one wishes for more emotion and adrenaline. The sporty expectation is naturally also created by the Tuono's racy appearance and cheeky demeanour. But this expectation is unfortunately not quite fulfilled in the saddle.

Easy-to-operate engine with good sound

successful appearance sporty handling

good ergonomics

decent brakes

extensive electronics - but partly at extra cost

stable and precise chassis

Price / performance ratio not right

IMU package costs extra
