Vehicle Information
Kawasaki KX80 Dirt Bike (1979-2000)
The Kawasaki KX80, a renowned motocross motorcycle, was produced from 1979 to 2000. Throughout its 21-year run, it consistently featured an 80cc two-stroke, single-cylinder engine, typically ranging from 79cc to 82cc. The KX80 underwent numerous significant updates to its engine, chassis, and features.
Initially launched in 1979 with an 82cc air-cooled engine and a dual-shock rear suspension, the model saw a major upgrade in 1981 with the introduction of Kawasaki's Uni-Trak single-shock system. A pivotal change occurred in 1983 when the engine became liquid-cooled, accompanied by an all-new chassis. Braking performance improved with a front disc brake in 1984 and a rear disc brake in 1988. Transmission evolved from a 5-speed in 1979 to a 6-speed in later models.
The primary variations were based on wheel size. The standard model featured smaller wheels, while the "Big Wheel" version, introduced in 1987, offered larger wheels (e.g., 19-inch front, 16-inch rear) and a longer swingarm, catering to taller riders. These changes reflect a continuous evolution rather than distinct generations. FAQ:
