The CL MotoTech RFY Shocks Technical Library brings together original shock reviews, rebuild information, spring-rate resources, and setup explanations for twin-shock motorcycles.
RFY designs and supplied components have varied over time. Each review describes the units inspected at the time; use the photos and measurements to identify your shocks rather than assuming every RFY-labelled unit has the same internals.
