2025 250cc Thoroughbred Racer

Yamaha’s race-tested YZ250 two-stroke is already known for its fast, powerful engine, plush suspension, class-leading handling and rider friendly character.
Its 249cc liquid-cooled YPVS-equipped reed-valve-inducted two-stroke engine is lightweight, compact and fun, with an incredibly wide, hard-hitting powerband; all housed within a carefully engineered, advanced aluminium frame for maximum track performance.
