Harley-Davidson's Reduced Effort Clutch Kit, sometimes called "Easy Effort," reduces the effort needed to squeeze the infamous Harley clutch lever by 30 per cent, and it is one of two products intended to decrease clutch pull. The reduced effort clutch has been standard equipment on all Twin Cam Harleys since the beginning of the 1996 model year. The reduced effort clutch kit installs on all Twin Cam 88 and Twin Cam B 88 motorcycles sold before 1996.
