Le anti-slip thermal clutch bells are equipped with an amateur reinforcement ring for heat dissipation that si develops mainly during le stationary da departures and when the vehicle accelerates from low speeds. SI is a technological innovation derived from research carried out in the field of scooter competitions. This is the principle on which si based: the larger radiant surface greatly lowers the operating temperature of the bell, considerably increasing the duration of the clutch group. The clutch group is enormously stressed in city routes, uphill departures and the exit da hairpin bends with two people on board. Here, for the protection of your clutch, Malossi has developed the Maxi Wing Clutch Bell. Not si should overlook the fact that the alettate reinforcement ring is even an anti-slip element, as it has been designed to withstand the high rotational speeds imposed on da a sports guide, especially if the engine has been processed, taking into account that the centrifugal force increases squared as the revolutions increase. TECHNICAL DATA Sweet steel sheet bell for deep molding; Special steel hub turned, welded and brocaded; Workplace turned within very narrow values; Total dynamic balancing; Heat treatment of soft nitride.
