Yamaha won its first World MX Championship before most of today’s aspiring young motocross riders were born – and we’ve always believed in building dirt bikes for everyone, from kids through to seasoned pros.
Featuring a race-bred specification that’s inspired by the flagship YZ450F, the new YZ65 youth motocross bike is the perfect start for any rider who is serious about racing. With an all-new engine and chassis, this high-tech 2-stroke delivers easy-to-use power together with stable handling for enhanced rider confidence.
Equipped with cool YZ450F-inspired bodywork, stylish Yamaha blue rims and an ergonomic riding position, the 2019 YZ65 is the choice of future champions.
