Vehicle Information
Yamaha PW80 Dirt Bike (1983-2006)
The Yamaha PW80, produced from 1983 to 2006, is a renowned youth off-road motorcycle designed for new riders. It features a reliable 79cc (or 80cc) two-stroke, air-cooled, single-cylinder engine paired with a 3-speed semi-automatic transmission and an automatic centrifugal clutch, simplifying gear changes.
Throughout its long production run from 1983 to 2006, the PW80 maintained remarkably consistent specifications. There were no distinct trim levels or significant mid-cycle generation changes. The model remained largely the same, with primary variations limited to cosmetic updates like graphics. The engine and transmission design remained unchanged, ensuring a consistent riding experience across all model years within this range. FAQ:
