Part Description
Fits Primo/Rivera Pro-Clutch and APM Competiton Master clutch on 1990-1997 Big Twin
Text excerpt from the catalog:
This variable pressure plate assembly increases pressure at higher RPM. Less effort is required to pull the clutch lever while shifting. Under the influence of high horsepower a dramatic increase in clutching power is obtained. Up to 60% more clutch pack compression allows to use a lighter diaphragm clutch spring. These TPP Variable Clutches are only to be used in combination with our Rivera Pro Clutches. TPP Variable Clutches for other applications are listed separately.
