Friction & steel drive plate kit. Extra plate sets have been a favorite amongst high performance bike owners for years. With the same clutch spring pressure the additional plates create more surface area which increases clutch holding capacity; a quicker lock-up and improved heat absorption. The clutch friction plate set includes a ''G3'' friction plates (incl. 6 friction plates and 3 jutter plates). G3 is a newly developed friction material that offers as good or better performance than the Alto Carbonite clutch material. It is formulated with graphitic carbon-based particles which is the most durable; consistent with improved shifting and reduced burn-out product to date for high horsepower and torque applications. Incl. 8 x 581916 (0.107/2.72mm friction); 3 x 581909 (0.151"/3.84mm) friction jutter plates and 9 x 581920 (0.056"/1.42mm thick) steel drive plates and 1 x 518914 (0.079"/2.01mm thick).
