The Honda XR500R represents the genesis of the modern four-stroke off-road machine. Produced from 1979 to 1984, it was the bike that truly launched the four-stroke revolution in the dirt, proving that high-performance off-road capability didn’t require a two-stroke engine. Built as the pioneer of the RFVC (Radial Four Valve Combustion) era, the XR500R set the benchmark for rugged simplicity and legendary low-end grunt. It remains a prized piece of off-road history, representing an era where mechanical purity was defined by raw, air-cooled power and a chassis designed to handle the unknown.
We encounter the same hurdles with nearly every restoration: intake boots that have hardened to the point of failure, airbox tabs sheared away by decades of trail use and vibration-absorbing grommets that have dried up or torn. It is standard to discover these machines with missing trim fasteners or faded plastics. Because most of these factory parts are now NLA (No Longer Available), owners are often left scrounging for used parts that are just as brittle and aged as the ones they are trying to replace.
This page features reproduction parts re-engineered specifically for the XR500R. We focus on matching or improving upon original OEM specifications by utilizing advanced, automotive-grade polymers. Our goal is simple: to provide reliable, direct-fit replacements that keep your XR on the trail and prevent it from becoming a “parts bike.”
Our XR500R components are often cross-compatible with the broader RFVC lineage, offering direct-fit solutions for the XR600R, NX650 Dominator or the XL600R.
