Poway Motorcycle has developed an extra plate clutch kit for the Honda Grom motors. This kit provides 17% more surface area for those big motor kits. The kit comes with 5 steel clutch plates, 6 fiber clutch plates, and a set of clutch springs. We have to machine the clutch pressure plate and the clutch center to except the two extra plates. You must send these pieces to use for machining. The cost of the kit is $203.95 plus tax and shipping. Call or email with questions.
