Specifically engineered for the KTM, Husqvarna, and Gas Gas 300 family—spanning from the classic carbureted models to the latest TPI and fuel-injected platforms—this Standard Series forged kit is the professional choice for a top-end refresh. At Moto-House MX, we know that 300cc riders demand low-end torque and long-term reliability; Wossner’s aerospace-grade forged components provide the strength and thermal stability needed for grueling enduro trails and high-speed desert loops.\u003c\/p\u003e\n\n\u003cp\u003eForged from premium aluminum alloy, the 8327DA features a dual-ring design. This configuration is preferred for 300cc woods and off-road bikes as it provides superior heat transfer to the cylinder wall and improved secondary compression, resulting in a broader powerband and increased piston stability. Wossner’s optimized machining ensures the piston remains lightweight for quick throttle response while maintaining reinforced crown and skirt walls. The permanent skirt coating reduces internal friction and piston rock, ensuring a quieter engine and a more efficient break-in. This Size A piston (71.94mm) is precision-matched for 72.00mm bores, making it the ideal solution for cylinders that are new or within factory-fresh tolerances.\u003c\/p\u003e\n\n\u003ch3\u003eTop Features: Wossner 8327DA Piston Kit\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eSize A (71.94mm):\u003c\/b\u003e Precision-engineered for 72.00mm bores to maintain factory-spec clearances and maximize engine life.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eDual Ring Design:\u003c\/b\u003e Enhances heat dissipation and improves sealing for the consistent, tractor-like torque 300cc riders rely on.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eAerospace-Grade Forging:\u003c\/b\u003e Offers significantly higher durability and fatigue resistance than OEM cast pistons, essential for high-load off-road riding.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eLow-Friction Skirt Coating:\u003c\/b\u003e Permanent molybdenum disulphide coating protects the cylinder wall and reduces wear during high-heat operation.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eOptimized Strength-to-Weight:\u003c\/b\u003e Engineered for lightness to improve engine response without sacrificing structural integrity.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eComplete Assembly:\u003c\/b\u003e Kit includes the forged piston, high-performance rings, wrist pin, and circlips.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eExpert Pro-Tip:\u003c\/b\u003e The KTM\/Husqvarna\/Gas Gas 300 engine is legendary for its longevity, but a fresh top end is the only way to keep your \"300\" feeling like a new bike. Size A is the correct choice for a cylinder that is in perfect condition or has just been replated. During installation on TPI or fuel-injected models, ensure your power valve is cleaned of carbon build-up for smooth operation. Pairing this build with a fresh top-end gasket kit and premium premix oil will ensure your machine continues to dominate the technical trails.\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\u003eYear Range\u003c\/th\u003e\n            \u003cth\u003eVehicle Brand\u003c\/th\u003e\n            \u003cth\u003eVehicle Model\u003c\/th\u003e\n        \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e2006-2023\u003c\/td\u003e\n            \u003ctd\u003eKTM\u003c\/td\u003e\n            \u003ctd\u003e300 XC \/ XC-W \/ EXC \/ TPI \/ Six Days \/ Erzbergrodeo\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e2014-2023\u003c\/td\u003e\n            \u003ctd\u003eHusqvarna\u003c\/td\u003e\n            \u003ctd\u003eTE300 \/ TE300i \/ TX300 \/ TX300i\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e2021-2025\u003c\/td\u003e\n            \u003ctd\u003eGas Gas\u003c\/td\u003e\n            \u003ctd\u003eEC 300 \/ EX 300 \/ MC 300\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 71.94mm piston designed for the standard 72.00mm bore.
