EBC 2009 Yamaha YZF R1 (1000cc) CSK Coil & Diaphragm Spring Kit — CSK211

EBC CSK Clutch Springs

Sold as a kit

New EBC CSK clutch springs prevent damage from prolonged exposure to heat and wear. They are OEM upgrades and are 10 percent stiffer than stock. The lever will be slightly stiffer which can wear your hand out riding in heavy traffic, but in return the clutch engages smoother and faster with the stiffer springs making takeoff smooth and shifting faster and less effort to speed shift.
