The cover comes with an additional in-built bearing and clutch nut (replaces original nut) for extra support of the drive shaft. Overall rigidity and balancing are improved, the torque drive runs more smoothly and power transmission is more reliable and efficient. In addition, Polini cut some rather big venting holes into both sides of the cover to improve air circulation and cooling. This leads to a sufficient intake of cool air and quick discharge of warm air to cool the transmission down. Please note that the cover does not include dowel pins and kick starter components. You can either keep the original parts or order them separately (under Related Products). Suitable for Minarelli engines with long case (type MA \/ MY).\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: Polini\u003c\/li\u003e\n\u003cli\u003eAvailability: Currently not in stock\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Polini","offers":[{"title":"Default Title","offer_id":53460826816855,"sku":"variator-cover-polini-big-evolution-mbk-nitro-aerox-black","price":428.4,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/4027\/5287\/files\/716643_6621939.jpg?v=1777832964","url":"https:\/\/mattmoto.pl\/en\/products\/variator-cover-polini-big-evolution-mbk-nitro-aerox-black","provider":"MattMoto Skutery","version":"1.0","type":"link"}
