{"product_id":"79cc-4-stroke-aluminium-cylinder-kit","title":"79cc 4-Stroke Aluminium Cylinder Kit","description":"The Malossi M3117771 is a 79cc aluminum racing cylinder kit designed for 4-stroke, 50cc Piaggio and Vespa engines. Constructed from a primary aluminum alloy with a high silicon content and tempered for durability, it features a cylinder liner with a silicon carbide coating in a galvanic nickel die, enhanced with crossed smoothing and two diamond passages for precise tolerances. The cylinder is meticulously machined on high-precision numerical control machines. The accompanying piston is crafted from a special low-thermal-expansion aluminum alloy with a tin facing on its sliding surfaces, and has been lightened and reinforced with upgraded heat exchange surfaces. It utilizes a 3-ring setup, including a nitrided and chromium steel compression ring, a special cast iron second ring, and a three-piece scraper ring made of chromium-plated special steel alloy.\n\nInstallation of this cylinder kit requires specific Malossi INJTRONIC control units depending on the model and emissions standard. For example, certain Piaggio Liberty 50 ie 4T euro 3 (2016-2017) models require art. 5517477B, while euro 4 and euro 5 variants of Piaggio and Vespa models will need different INJTRONIC units (art. 5518409, 5519266B, or 5520202B) as specified in the product details. This product is reserved exclusively for racing use in designated locations and Malossi disclaims all liability for improper use.","brand":"Malossi","offers":[{"title":"Default Title","offer_id":52688999940408,"sku":"M3117771","price":268.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687501984.jpg?v=1784900149","url":"https:\/\/store.motormia.co\/products\/79cc-4-stroke-aluminium-cylinder-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
