Yamaha XSR900 GP 2025

Credible styling in the style of the 500 GP machines from around 1990 meets state-of-the-art components from the CP3 modular system. For the suspension components, Yamaha used high-quality, fully adjustable parts from KYB. The fork is the same as that used in the MT-09 SP. The sporty basic set-up is perfectly suited to this pretty retro racer. The standard electronic features are also impressive. All riding aids are lean angle-dependent, the quickshifter works first-class and there is even cruise control on board. If you can cope with the sporty riding position, you can enjoy a dream bike. Apart from the brakes, which could have a little more bite, we have no real criticism to make.

The mere fact that the Kawa Ninja ZX-4RR with its high-revving Inline four-cylinder engine in bonsai format has no real competition makes it absolutely unique. The engine is also the absolute flagship, with a rev limit at 16,000 touring you'll be addicted to wind out a gear! The suspension, brakes and electronics are of a high height, but what is more surprising is that, despite all the sportiness, the bike is still very suitable for everyday use - the seating position is not as radical as on other supersports bikes.

Fun in-line four-cylinder

precise quickshifter with blipper

balanced handling

sporty and pleasant ergonomics

comprehensive electronics package

Engine needs to be kept happy

looks confusing with other Kawasakis
