Vehicle Information
Kawasaki KX420 Dirt Bike (1980-1982)
The Kawasaki KX420, a formidable 2-stroke motocross motorcycle, was produced from 1980 to 1981, with some debate surrounding a 1982 model year. This open-class dirt bike featured a 422cc single-cylinder engine paired with a 5-speed transmission, designed for competitive off-road riding. A significant innovation for its time, the Uni-Trak rear suspension system, was introduced in 1980. The 1980 KX420-A1 faced criticism for its weight, handling, and engine performance, notably experiencing frame breakage issues. Kawasaki addressed some of these concerns in the 1981 KX420-A2 with minor updates, including a redesigned swingarm and additional frame bracing, particularly around the steering stem. Despite these improvements, the engine largely carried over, and the 38mm forks were considered undersized. The existence of a 1982 model is contested; while some sources suggest Kawasaki paused open-class production, others list a 1982 KX420-A1, which, if released, also received poor reviews for its frame and engine. Q: How do I ensure I select the correct parts for my KX420?
