Show original supplier description
The STM Wet Slipper Clutch is engineered to enhance the performance and longevity of your Yamaha YZF-R7 (2021-2025). This advanced clutch system leverages STM's proprietary 'Ball & Ramp' actuation technology, ensuring exceptionally smooth slipper clutch operation. This reduces the risk of rear-wheel hop during aggressive downshifts, providing more control and confidence. Further setting this clutch apart is STM's exclusive 'FLS', or Forced Lubrication System. The FLS actively increases the flow of engine oil through the wet clutch assembly. This enhanced lubrication leads to significantly cooler operating temperatures and a cleaner clutch environment, which directly translates to improved performance and extended component life. The system is designed for direct installation, requiring the use of a steel conducted disc with the original Yamaha part code 5VY-16325-00 for proper mounting.
