Vehicle Information
Yamaha MX80 Dirt Bike (1980-1982)
The Yamaha MX80, produced from 1980 to 1982, is a lightweight and robust off-road motorcycle, designed for beginners and recreational riding. Powered by a 72cc two-stroke, single-cylinder engine producing approximately 4 horsepower, it features a 4-speed transmission. This model served as an excellent entry point into the world of motocross for many young riders. While the core engine specifications remained consistent from 1980 to 1982, a notable distinction was made in the model's classification. The 1980 (MX80G) and 1981 (MX80H) versions were identified as "Dirt (not MX)" bikes, whereas the 1982 MX80J was classified as a "Moto Cross" model. This classification change does not indicate significant alterations to the engine or fundamental design. Q: How can I ensure this part fits my Yamaha MX80?
R: To ensure compatibility, please use our year and edition selector located at the top of the page.
