Description
The Big Evolution variator cover by Polini is a state-of-the-art technical masterpiece, with stunning looks to boot.
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).
CVT cover
Although variator covers do not belong to the classic wear parts, they can be damaged and must be replaced. You can also replace the original cover with a stylish custom model.
Tuning CVT cover
Custom covers are available in different colours and designs, which of course won't improve performance. There are transmission covers with cutouts that provide better ventilation and cooling for tuned engines.
