It’s the first major redesign of the YZ125 for 15 years – and Yamaha has gone to town on it with a heavily revised engine, new styling, new subframe and much more. And the YZ250 also gets the slick new look, bodywork and subframe to change how it feels. Former British 125 and 250 two-stroke champion Dave Willet tests the stock 2022 YZ125 and YZ250, and also GYT-R kitted versions of the bikes, on the Dorno track in Italy.
