Friends of real supersports bikes listen up, because the Yamaha YZF-R125 could be just the right bike for you in the A1 class. The Yamaha focuses entirely on a sporty appearance, which is not only evident in the R6-like look, but can also be felt in the seating position. The load on the wrists is super-sporty and the knee angle is sharp - perhaps too sharp for tall riders. In return, the YZF-R125 rewards not only with a cool appearance, but also with a very potent engine and a confidence-inspiring chassis that invites high cornering speeds.
