STM Clutch cover for Yamaha YZ250 1999-...

CLG CLUTCH STM has achieved maximum performance thanks to the R&D department in collaboration with the best teams in the MXGP World Championship, reaching out the maximum performance following an R&D evolution in 4 steps: - 1 aluminium (light) - 2 aluminum and steel (light and durable) - 3 skeletonized steel (+ light + durable) - 4 optimized skeletonized steel OFFROAD CLG CLUTCH The evolution of materials has highlighted how it is possible to obtain components of greater lightness and durability through an in-depth study of deformations and the optimization of geometries. The new design introduces a completely innovative clutch concept, ensuring the following advantages: - High lubrication of all components - Customization of the clutch using the famous STM spring - Greater resistance - Greater durability - Lightness - Lower rotational inertia - Lower oil temperature - Improved smoothness of the discs
