Malossi Sport 70cc 47mm Cylinder Kit with Head – Minarelli Vertical Pin 10

The Malossi Sport 70cc 47mm cylinder kit is a reliable and powerful upgrade for Minarelli vertical 2-stroke engines. This kit is supplied complete with the Malossi cylinder head.

With a 47 mm bore, the cylinder increases displacement to approximately 70cc, providing noticeably stronger acceleration and torque compared to the original 50cc setup.
