The YZ250 is a two-stroke motocross race bike made by Yamaha. The model was launched in 1974, and has been regularly updated and is still in production with new releases every year. The original YZ250 of 1974 used an air-cooled 250cc two-stroke engine of 70 mm bore and a 64 mm stroke, which was improved semi-annually. The air-cooled motor was replaced in 1982 with a 249cc liquid-cooled two-stroke reed-valved engine with a mechanical, rather than servo-driven, YPVS exhaust valve for a wider spread of power. Although other makes of contemporaneous motocross engines featured theoretically superior crankcase reed-valves, the YZ250 still has the reed-block integral to the cylinder.

Great example of this much loved four-stroke. Ready to go after it has had a full rebuild and new plastics by the current owner.
