Vehicle Information
Honda XR500R Dirt Bike (1981-1984)
The Honda XR500R, produced from 1981 to 1984, was a high-performance off-road motorcycle known for its robust air-cooled, four-stroke, single-cylinder engine, consistently displacing 498cc (or 497cc) across all years. It featured a 5-speed transmission. While there were no distinct "trims" in the modern sense, the XR500R received significant yearly updates. The 1981 model marked a major redesign, introducing Honda's Pro-Link single-shock rear suspension, a new frame, and an engine with an intake-mounted reed cage for improved low-end power. Wheel sizes were also updated to 21-inch front and 17-inch rear. A substantial overhaul occurred in 1983, bringing a lighter, more powerful dry-sump RFVC (Radial Four Valve Chamber) engine, a revised frame, dual carburetors, and a front disc brake. The 1982 and 1984 models primarily featured minor cosmetic changes and suspension refinements. The 1984 model was the final year for the XR500R before the introduction of the XR600. FAQ:
