ABSTRACT:
A clutch device for a motorcycle includes a body, at least two centrifugal weights pivotably mounted on a side of the body, and at least two springs. Each centrifugal weight includes a through-hole extending from an inner side thereof through the outer periphery face thereof. A spring-attaching member is mounted in the through-hole of each centrifugal weight and includes a first end and a second end that has a screw hole. An adjusting screw is mounted in each spring-attaching member. Each spring includes a first end attached to an associated centrifugal weight and a second end attached to the first end of the spring-attaching member on another centrifugal weight. Each spring-attaching member moves along a longitudinal direction of an associated through-hole when an associated adjusting screw is turned, thereby adjusting tightness of an associated spring.
