Malossi MHR 70ccm Cylinder Kit for Piaggio LC – Consumer Racing with Real Pressure

If you want to get the maximum out of your Piaggio LC setup, the Malossi MHR 70ccm Cylinder Kit is exactly your thing: Malossi's most powerful consumer racing cylinder with substantial performance potential. With a 47.6 mm bore and 6 transfer ports, the kit is clearly designed for performance – depending on the setup, up to approx. 20–21 hp is possible.

The cylinder is particularly popular for setups on Piaggio Zip SP LC, Gilera Runner 50 LC, or Aprilia SR 50 LC – in other words, everywhere a Piaggio engine with water cooling cries out for more RPM and acceleration.
