Displacement is 49cc, with a 41mm bore and a 37.4mm stroke. A continuously variable (CVT) automatic transmission drives the engine, which can be started either electrically or by kick.\u003c\/p\u003e\u003ch3\u003eReplacement Considerations\u003c\/h3\u003e\u003cp\u003eSigns that the piston may need attention include reduced power and heavy exhaust smoke. Staying on top of routine upkeep and replacing worn parts when needed can help the engine perform better over time. This kit is designed to drop into the existing setup, so it is a simple job for anyone comfortable with scooter maintenance.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Outer Diameter:\u003c\/strong\u003e 47mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Piston Height:\u003c\/strong\u003e 45mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompression Height:\u003c\/strong\u003e 19mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWrist Pin Diameter:\u003c\/strong\u003e 10mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWrist Pin Length:\u003c\/strong\u003e 39.8mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Piston, pin, rings, circlips\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Morini AD50 engines on Hyosung, Suzuki and TGB street scooters, and Morini 70cc 2-stroke engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMorini AD50 engine (49cc, 2-stroke, 41mm bore) on Hyosung, Suzuki and TGB street scooters\u003c\/li\u003e\n\u003cli\u003eAprilia, Italjet, KTM, Malaguti and other Moto Morini \/ Franco Morini engines (listed by the seller)\u003c\/li\u003e\n\u003cli\u003eBenelli 491 ST\u003c\/li\u003e\n\u003cli\u003eDerbi Vamos\u003c\/li\u003e\n\u003cli\u003eItaljet Formula 50, Formula 50 LC, Torpedo 50, Velocifero 50\u003c\/li\u003e\n\u003cli\u003eMalaguti Crosser CR1\u003c\/li\u003e\n\u003cli\u003ePeirspeed Bolero, Delivery, Key Largo, Key West, Laser R5, Laser R9, Outback, R50X, RM50, Sunset\u003c\/li\u003e\n\u003cli\u003eSuzuki Address 50, AP50, AZ50, Hi-Up, Lets II, Mollet 50, SJ50-QT, Sepia 50, Sepia ZZ, Street Magic, TR50, Verde, ZZ\u003c\/li\u003e\n\u003cli\u003eMorini 70cc 2-stroke\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eHow to choose:\u003c\/strong\u003e Confirm that your engine's bore is 47mm, then match the 47mm piston outer diameter and 10mm wrist pin to your setup before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShop more:\u003c\/strong\u003e \u003ca href=\"\/collections\/scooter-pistons-rings\"\u003eScooter Pistons \u0026amp; Piston Rings\u003c\/a\u003e · \u003ca href=\"\/collections\/scooter-parts\"\u003eScooter Parts\u003c\/a\u003e\u003c\/p\u003e","brand":"Trend Times Toy Stores","offers":[{"title":"Default Title","offer_id":51134473961529,"sku":"TT-16001","price":17.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/3358\/9049\/files\/morini-47mm-piston-kit-1.webp?v=1794344403","url":"https:\/\/www.trendtimes.com\/products\/morini-47mm-piston-kit-for-scooters-mopeds","provider":"Trend Times Toy Stores","version":"1.0","type":"link"}
