Patent number: 4817452Abstract: The invention provides a simple method for reducing the amount of force required to actuate a motorcycle clutch. A miniature, lightweight housing means provides a pivot for a lever means to which is attached a short cable from the clutch actuation handle and also the original cable from the clutch. Because the two cable attachment points on the lever means are staggered, the lever means provides mechanical advantage and thereby reduces the manual force required to move the clutch actuation handle.The invention is designed to allow fast installation by providing cable slots in all parts and using cable sleeve tension to permit simple hook-on attachment of cable terminal hardware to the lever means. The housing means cover is used to exclude the environment and also to assure mechanical strength. The pivot pin and attachment hardware for anchoring the cables is locked into place by the covers.Type: GrantFiled: July 13, 1988Date of Patent: April 4, 1989Inventor: Ronald L. Burkey
