Specifically engineered for modern European 2-strokes including KTM, Husqvarna, Beta, and Gas Gas, this Standard Size A forged kit is the professional choice for restoring Factory Quality power. At Moto-House MX, we know that small-bore engines demand the highest quality components to survive the high-RPM stress of motocross and off-road racing; Wossner’s aerospace-grade forged alloy delivers exactly that.\u003c\/p\u003e\n\n\u003cp\u003eForged from aerospace-grade aluminum alloy, the 8220DA offers superior structural integrity and heat resistance compared to standard cast pistons. This kit features a permanent skirt coating to reduce internal friction and piston rock, resulting in a quieter engine and smoother throttle response. This Standard Size A piston (53.95mm) is designed for cylinders with a 54.00mm bore, providing the precise clearances needed for optimal performance in new or freshly plated cylinders.\u003c\/p\u003e\n\n\u003ch3\u003eTop Features: Wossner 8220DA Piston Kit\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eStandard Size A (53.95mm):\u003c\/b\u003e Precision-engineered for 54.00mm bores to restore original factory tolerances and compression.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eAerospace Forged Alloy:\u003c\/b\u003e Premium aluminum construction built to withstand the mechanical stress and heat of competitive 125cc racing.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eLow-Friction Skirt Coating:\u003c\/b\u003e Permanent coating reduces wear on cylinder walls and ensures a more efficient break-in period.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eSingle-Ring Performance:\u003c\/b\u003e Optimized for reduced drag and maximum high-RPM efficiency in 125cc race applications.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eComplete Assembly:\u003c\/b\u003e Kit includes the forged piston, high-performance ring, wrist pin, and clips.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eExpert Pro-Tip:\u003c\/b\u003e In the 125cc class, the piston is a high-wear item that requires regular intervals of replacement to prevent cylinder damage. Size A is the correct choice for a new cylinder or a cylinder that has just been replated. When installing the 8220DA, always check your ring end gap and replace your small-end wrist pin bearing. Using a fresh top-end gasket kit is essential for maintaining the primary compression needed for that signature 2-stroke snap.\u003c\/p\u003e\n\n\u003ch3\u003eFitment List\u003c\/h3\u003e\n\u003ctable border=\"1\" cellpadding=\"8\" style=\"width: 100%; border-collapse: collapse;\"\u003e\n    \u003cthead\u003e\n        \u003ctr\u003e\n            \u003cth\u003eBrand\u003c\/th\u003e\n            \u003cth\u003eModels\u003c\/th\u003e\n            \u003cth\u003eYear Range\u003c\/th\u003e\n        \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cb\u003eKTM\u003c\/b\u003e\u003c\/td\u003e\n            \u003ctd\u003e125 SX \/ XC \/ XC-W \/ EXC \/ Six Days\u003c\/td\u003e\n            \u003ctd\u003e2001-2022\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cb\u003eHusqvarna\u003c\/b\u003e\u003c\/td\u003e\n            \u003ctd\u003eTC125 \/ TE125 \/ TX 125 \/ Heritage\u003c\/td\u003e\n            \u003ctd\u003e2014-2025\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cb\u003eBeta\u003c\/b\u003e\u003c\/td\u003e\n            \u003ctd\u003e125 RR \/ Race Edition \/ X-Pro\u003c\/td\u003e\n            \u003ctd\u003e2018-2026\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cb\u003eGas Gas\u003c\/b\u003e\u003c\/td\u003e\n            \u003ctd\u003eMC 125\u003c\/td\u003e\n            \u003ctd\u003e2021-2025\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e\u003cb\u003eHusaberg\u003c\/b\u003e\u003c\/td\u003e\n            \u003ctd\u003eTE125\u003c\/td\u003e\n            \u003ctd\u003e2012-2014\u003c\/td\u003e\n        \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eQ: Is this a Standard Size piston?\u003c\/b\u003e\u003cbr\u003e\nA: Yes, this is the 53.95mm piston designed for the standard 54.00mm bore.
