Malossi MHR 70cc Cylinder Kit for Minarelli 2-Stroke Scooters
This Malossi MHR 70cc cylinder kit is designed for air-cooled, horizontally mounted Minarelli 2-stroke engines. It raises displacement from 50cc to 70cc, which can deliver a noticeable gain in performance. If you are browsing Minarelli 50cc and Yamaha Jog scooter parts, this kit is one option that can enhance how your scooter rides. Its components are built from hard-wearing materials, making it a dependable upgrade across several models.
Construction and Components
The cylinder uses an aluminum body with a Nikasil lining, which reduces friction and helps the metal shed heat more effectively. The kit includes an HTSR aluminum cylinder head, which is built to racing specification. A 47mm Asso forged piston is also included, chosen for toughness and consistent operation. Remaining parts are a 10mm wrist pin with a needle bearing, two piston rings, a circlip, a base gasket, and a head gasket.
Installation and Replacement
Fitting the Malossi MHR kit is simple for anyone comfortable working on engine assemblies. It suits situations where worn or underperforming top-end parts need replacing. Many riders pick this kit to add power, whether for track use or everyday riding.
