This 4-stroke cylinder from Malossi is made of aluminum and then covered with a Nickasil coating. It has a displacement of 66.3cc thanks to the use of a 44mm diameter piston on its original stroke which is 43.6mm. In order to best use the capabilities of this cylinder, we recommend the use of a Malossi Force Master CDI box in addition (5518429).
