Designed as a cast original-equipment replacement piston, this kit provides a dependable fit and durable performance for engine rebuilding and routine maintenance. The piston is manufactured from gravity-cast aluminum alloy with an 18% silicone content, offering the material characteristics needed for demanding two-stroke applications.\u003cbr\u003eThe piston undergoes a T-5 heat-treatment hardening and tempering cycle to help improve strength, durability, and resistance to operating stresses. Its skirt features a high-tech molybdenum disulfide coating that helps reduce friction during initial operation, promotes faster break-in, and contributes to extended piston life. This coating is especially beneficial when restoring engine performance after a piston replacement or top-end service.\u003cbr\u003eThe Vertex S4C05800003B kit includes the essential components needed for installation: one piston, piston rings, a wrist pin, and circlips. The 66.35 mm piston size is engineered for compatible Suzuki RM250 applications, but fitment should be verified against the motorcycle model year, cylinder specifications, and manufacturer service requirements before installation. Proper assembly, clearance checks, lubrication, and break-in procedures are recommended for the best results.\u003cbr\u003eFeatures include a cast OE replacement design, heat-treated aluminum construction, and a friction-reducing piston skirt coating. With its complete component package and application-focused engineering, the Vertex Piston Kit offers a practical solution for maintaining consistent engine operation and renewing the top-end of a compatible Suzuki RM250.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBrand: Vertex\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePart Number: S4C05800003B\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication: Compatible with Suzuki RM250 models\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePiston Size: 66.35 mm\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstruction: Gravity-cast aluminum alloy with 18% silicone content\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeat Treatment: T-5 hardening and tempering cycle\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSkirt Coating: Molybdenum disulfide coating for faster break-in and reduced friction\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesign: Cast original-equipment replacement piston\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eKit Contents: Piston, rings, wrist pin, and circlips\u003c\/li\u003e\u003c\/ul\u003e\r\n\u003cp\u003eShips from Parts Unlimited.\u003c\/p\u003e","brand":"Vertex","offers":[{"title":"Default Title","offer_id":60117675901214,"sku":"S4C05800003B","price":230.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1091\/7884\/7518\/files\/408340.png?v=1791108829","url":"https:\/\/shoplepier.com\/products\/vertex-piston-kit-66-35-mm-for-suzuki-rm250-part-number-s4c05800003b","provider":"LEPIER POWERSPORTS","version":"1.0","type":"link"}
