Strengthened clutch bell with patented cooling concept. The air flows through the side fins and the enlarged drills to the clutch facings. This results in longer life for the clutch and reduced clutch slip when the engine is warm. The bell's temperature will be considerably lower which leads to less waste energy and higher performance at the rear wheel. Better acceleration also with warm engine. The bell interior was sand streamed to increase the linings' grip. The lower mass of only 395g (compared with Malossi Wingbell 575g, Polini Evolution 485g) has positive effects on the engine's acceleration.

ATTENTION !!! Fits only Minarelli engines that come with 3 shoe clutches as standard fitting (inner diameter of the bell = 107mm), please check before ordering.
WB-5495 ; WB-5476 ; WB-5427 ; WB-5499 and the universal clutch holding tool will fit.
