Rivera Primo's "CENTRI-FORCE" fully centrifugal auto clutch instantly HOOKS UP between 1100 -1500 rpm's for hard charging no slip clutch action, but the stall speed is adjustable. The clutch handle stays against the handgrip at idle, but goes to its normal stand-off position when accelerating. Perfect for the street or strip "CENTRI-FORCE" can be shifted normally, or shifted without touching the clutch lever using the "power off technique." Totally eliminates "gorilla grip" clutch effort at the lever. Easy to install, "CENTRI-FORCE" replaces the original Rivera Primo pressure plate, diaphragm spring, spring and retainer. Consistent "Hole Shots" every time. Great for jockey shift applications. Requires 6 holes to be drilled and tapped in the lip of the clutch basket prior to installation (except on Brute IV Extreme & chain drive applications).
