HINSON Hi-Temps Clutch Spring Kit (Manufacturer part number: CS663-1-2101) — a set of springs designed for demanding motocross riders.

• Formulation and geometry aimed at providing a consistent grip while minimizing heat buildup.
• Tight production tolerances for repeatability and precise fit in the clutch basket.
• Developed for use on Hinson components as well as, unless otherwise specified, with stock clutch parts.
• Designed and manufactured in the United States.

Ideal for motocross and off-road practices, this kit is aimed at riders seeking a reliable and smooth clutch feel under race conditions. Check compatibility with your model before installation — mentioned among others on Kawasaki KX 450 (2022, 2026) and KX 450 X (2026). For serious maintenance or preparation of your transmission, these Hinson springs are a high-performance and proven option in competition.
