Hinson Hi-Temps clutch spring kit Clutch springsRef : HI00009A / 1118473

HINSON Hi-Temps Clutch Spring Kit (manufacturer part number: CS357-5-0109) — springs designed for motocross bikes, engineered to withstand the extreme conditions of modern four-strokes. Developed by HINSON and manufactured in the USA, these springs combine temperature resistance and consistent return for more predictable clutch behaviour on the track.

• High-temperature steel: resistance to loss of strength during heat build-up.
• Optimised grip: better bite and consistency of the engagement point without excessive thermal accumulation.
• Tight production tolerances for repeatability and reliable installation.
• Designed to be compatible with Hinson components and aimed at improving the performance of the original clutch.
• Compatible with most OEM parts, unless otherwise stated by the manufacturer.
• American manufacturing: quality control and premium materials.

Ideal for demanding motocross riders looking to enhance clutch control and feel at the lever. Recommended reference for models such as the Suzuki RM-Z 250 (2026) and Kawasaki KX 250 / KX 250 X (2024). Be sure to check compatibility with your clutch housing before installation.
