The DPK series of Dalton flyweights was designed to fit the Kawasaki ATV drive clutch. Better distribution of mass allows for excellent belt grip on the bottom end, while maintaining top rpm. Now available in more base gram increments. These weights are adjustable by use of mass rivets (DFR-Y). The DPK series does not fit the '08 BF 750 model or the Teryx utility. These models use a new improved drive clutch on the engine.
