67mm Bore 47mm Stroke 166cc Aluminum Cylinder Kit

The Malossi 3115326 is an aluminum cylinder kit designed for 4-stroke liquid-cooled engines. It features a bore of 67mm and a stroke of 47mm, resulting in a displacement of 166cc. The kit includes a piston with a 15mm pin and is constructed from a primary aluminum alloy with a high silicon content for improved heat exchange and low thermal expansion.

The piston rings are made from special materials for high sliding properties and mechanical resistance, including nitrided and chrome-plated steel for the compression ring. This cylinder kit is designed for performance applications and requires the use of a Malossi Force Master 2.1 control unit for installation.
