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.
