Yamaha XSR900 2018

Yamaha XSR900 2018

The Yamaha XSR900 is a classic optical illusion - with its round headlight, angular tank and attached tail light, it clearly passes for a retro bike. But it's no coincidence that the performance is reminiscent of the potent mid-range naked bike Yamaha MT-09, which is the extremely sporty basis for the XSR900. So the engine is a blast and the brakes are appropriately venomous. Fortunately, the engineers didn't overdo it with the chassis, the XSR900 offers sufficient comfort and the upright riding position is more comfortable than the powerful engine would lead one to expect. All in all, the XSR900 is one of the sportiest models among the retro bikes.

Ducati Streetfighter V4 S 2021

The problem of the Streetfighter V4 S with Euro4 engine, namely no power in the lower rev range but explosion in the upper rev range, has been largely rectified with the update to Euro5. Although the disgusting 208 hp are still only available at 13,000 rpm, the SF V4 S now also works acceptably at lower revs. The electronic Öhlins suspension is at its best and the brute Brembo Stylema stoppers again celebrate the penchant for the racetrack. Ergonomics and handling are also basically good, but on the racetrack you would wish for lower handlebars because of the awesome power. A perfect poser bike that also works on the country road, and on the racetrack anyway. Only the too-loud sound should be curbed a little.

The most powerful naked bike ever
