This 53.96mm forged piston is specifically engineered for cylinders that have experienced natural wear, ensuring the precise piston-to-wall clearance required for maximum 2-stroke power. At Moto-House MX, we provide the technical components champions rely on to keep their high-revving 125cc machines at the head of the pack.\u003c\/p\u003e\n\u003cp\u003eForged from aerospace-grade aluminum alloy, this piston offers a superior strength-to-weight ratio, allowing it to withstand the extreme RPMs of competitive 125cc racing. The permanent skirt coating is a vital feature, reducing internal friction and piston rock for a quieter engine and smoother power delivery. The single-ring design of the 8056DB is optimized for reduced drag and high-RPM efficiency, ensuring your KTM stays crisp and responsive on every gate drop.\u003c\/p\u003e\n\u003ch3\u003eTop Features: Wossner 8056DB Piston Kit\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eStandard Size B (53.96mm):\u003c\/b\u003e Precision-sized for cylinders with a 54.01mm bore to maintain optimal mechanical clearances.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eAerospace Forged Alloy:\u003c\/b\u003e Premium aluminum construction for maximum heat resistance and high-RPM durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eLow-Friction Skirt Coating:\u003c\/b\u003e Permanent coating reduces wear and mechanical noise for a more efficient engine.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSingle-Ring Racing Design:\u003c\/b\u003e Engineered for reduced friction and maximum performance in 125cc competition.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eComplete Kit:\u003c\/b\u003e Includes everything needed for a top-end refresh: forged piston, ring, wrist pin, and clips.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eExpert Pro-Tip:\u003c\/b\u003e 125cc engines are highly sensitive to piston clearance. Use a micrometer to verify your cylinder bore. If your cylinder has worn slightly beyond the \"A\" spec, the Size B piston will restore the tight seal needed to prevent power loss and piston slap.\u003c\/p\u003e\n\u003ch3\u003eFitment List\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse;\" cellpadding=\"8\" border=\"1\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eYear Range\u003c\/th\u003e\n\u003cth\u003eVehicle Brand\u003c\/th\u003e\n\u003cth\u003eVehicle Model \u0026amp; Size\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e2001-2006\u003c\/td\u003e\n\u003ctd\u003eKTM\u003c\/td\u003e\n\u003ctd\u003e125 SX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eQ: What is the benefit of a Size B piston?\u003c\/b\u003e\u003cbr\u003eA: Size B is 0.01mm larger than Size A.
