Vehicle Information
Yamaha YZ400 Dirt Bike (1976-1998)
The Yamaha YZ400, an iconic motocross motorcycle, underwent a remarkable evolution between 1976 and 1998. Initially launched as a powerful two-stroke model, it marked a major turning point in 1998 with the reintroduction of the YZ400F name, this time as a revolutionary four-stroke machine. This period covers models that defined their era, offering distinct performance for motocross riders. The two-stroke YZ400 (1976-1979) was a 397cc single-cylinder, with annual improvements such as a redesigned frame in 1977 and an aluminum swingarm in 1978. After 1979, the model was discontinued, replaced by the YZ465 and YZ490. The YZ400 name returned in 1998 with the YZ400F, a 399cc liquid-cooled four-stroke motorcycle, marking a new era for motocross. Q: How can I ensure parts fit my Yamaha YZ400?
