Hinson Racing Complete Billetproof Conventional Clutch Kit for Yamaha WR250F, YZ250F and YZ250FX (HC641-1901)

Upgrade clutch performance with the Hinson Racing Complete Billetproof Conventional Clutch Kit, part number HC641-1901. Designed for compatible Yamaha WR250F, YZ250F and YZ250FX applications, this precision-engineered kit is built to improve clutch durability, engagement quality and heat management under demanding riding conditions. The billet T-6 aircraft-quality aluminum construction is machined to aerospace tolerances for dependable fit and consistent operation.
The Hinson Racing Billetproof clutch design allows the clutch assembly to spin more truly when the clutch is disengaged, helping reduce heat buildup and promoting smoother operation. A more positive clutch engagement can improve control during starts, cornering and technical riding, while the design also helps eliminate clutch chatter for a cleaner, more predictable feel at the lever and rear wheel.
The clutch component is hard coated for up to five times the wear resistance of a stock component when properly maintained. This added surface protection helps the assembly withstand repeated clutch use and demanding operating conditions, supporting extended service life and consistent performance. The complete kit is a practical choice for riders seeking a durable clutch upgrade without sacrificing smooth engagement.
