About the Yamaha YX600
The YX600 code identifies the Radian; the individual part determines the year coverage.
Yamaha’s 1986 factory parts catalog identifies the Radian as YX600S and YX600SC. YX600 and Radian are connected model-code and model-name references, not evidence of two different motorcycles. Preserve the full year and market designation when comparing carburetor, electrical or chassis equipment.
Use the YX600 model code to match parts to the repair you are carrying out. The gasket set below lists 1986–1987 and the clutch plate lists 1986–1989, while the fork seals and brake parts extend through 1990. For brake work, identify the rear drum or the disc caliper being serviced. A multi-model product title still needs to include your exact YX600 application.
Compare the actual applicationYX600 part and year differences
The table compares selected YX600 applications only. Fork and brake coverage through 1990 does not extend the featured 1986–1987 gasket set or 1986–1989 clutch plate to that year. Confirm brake position as well as the model.

Identify the fitted equipmentYX600 code, year and fitted-part checks
- Record the complete Yamaha model designation and year; use the market-specific identification when available.
- Confirm the engine and front end belong to the motorcycle’s recorded model, especially on a restored Radian.
- Compare fork oil-seal profile and dimensions; distinguish disc brake pads from the listed rear drum shoes.
- For gaskets or clutch plates, check the exact year, included pieces or individual quantity, and the removed component’s shape.
