This aftermarket hub is made for KYOSHO FW05-R and FW05RR on-road kits and carries the part code FW05-RR008. Its reduced rotating mass helps the clutch pick up and drop off more distinctly, improving throttle feel.
The hub is shaped to the FW05-R/FW05RR clutch layout and aligns with factory mounting points. Verify spline engagement and shoe clearance prior to torqueing fasteners. Only use threadlocker where specified by your clutch component supplier.
When tuning, a lighter hub shifts slip characteristics, letting you refine launch and mid-corner throttle reapplication more easily. Work in small increments and compare lap data when changing springs or shoe compounds.
