YX600 and Radian Identify the Same Yamaha Family
This collection is built around the Yamaha YX600 Radian, the documented motorcycle behind the YX600 model code. Yamaha’s U.S. parts records list YX600S and YX600SC for 1986, YX600T and YX600TC for 1987, YX600U and YX600UC for 1988, YX600W and YX600WC for 1989, and YX600A and YX600AC for 1990. In those records, the added C identifies the California version. That complete suffix is important when checking fuel, intake, exhaust, electrical and emissions-related components.
Radian is the sales name and YX600 is the model code, but neither makes every component interchangeable across the full run. Some PartsNMore items cover multiple years while others apply only to selected variants. Use the fitment shown on the individual product page rather than treating this collection as a blanket all-year guarantee.
