EBC CSK39 clutch springs are designed as a replacement and performance-upgrade component for compatible Yamaha motorcycle clutch assemblies. The springs are 15% stiffer than the original equipment springs, helping minimize clutch slip and support improved power transfer to the ground.
By helping reduce clutch slip, these EBC clutch springs can also reduce clutch plate wear during operation. The CSK39 clutch spring set fits the 1993 and 1994 Yamaha YZ80; 1980, 1981, 1982, and 1983 Yamaha YZ100; 1973, 1974, and 1975 Yamaha RD350; and 1970 Yamaha R5.
