Aprilia RS 660 2021

Aprilia RS 660 2021

In 2021, the Aprilia RS 660 can be seen as the last true 600cc supersport, because with its sporty seating position and high-quality chassis components, it hits the sweet spot between suitability for everyday use and trackday potential. Thanks to the comprehensive electronics package, nothing is left to be desired on the road or on the track - and you can't complain about the powerful two-cylinder anyway. A great package for all those for whom 200+ hp superbikes are too much for everyday use.

Yamaha XSR900 GP 2024

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.
