Specifically engineered for the high-performance 450cc engines found in 2008-2012 KTM and Husaberg models, this Standard Series forged kit is the professional choice for restoring factory-spec power and reliability. At Moto-House MX, we know that 450cc riders demand consistent torque for everything from technical dual-sport trails to adventure touring; Wossner’s aerospace-grade forged components provide the precision and heat management needed to keep your engine running at its peak.\u003c\/p\u003e\n\n\u003cp\u003eForged from high-strength aluminum alloy, the 8707DA maintains a reliable 11.9:1 compression ratio, offering a perfect balance between aggressive power delivery and engine longevity. This kit features Wossner’s advanced radial boss machining and enhanced oiling slots for superior wrist pin lubrication—a vital feature for 4-stroke engines that endure long hours and high operating temperatures. The permanent skirt coating reduces internal friction and piston rock, resulting in a quieter running engine and a smooth break-in period. This Standard Size A piston (94.95mm) is precision-matched for 95.00mm bores, restoring your KTM or Husaberg to its original mechanical tolerances.\u003c\/p\u003e\n\n\u003ch3\u003eTop Features: Wossner 8707DA Piston Kit\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eStandard Size A (94.95mm):\u003c\/b\u003e Precision-engineered for 95.00mm bores to maintain factory-spec clearances and maximize engine life.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003e11.9:1 Compression Ratio:\u003c\/b\u003e Designed to match original performance specifications for reliable power delivery and compatibility with high-quality fuel.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eStandard Series Forging:\u003c\/b\u003e Significantly stronger and more resilient than OEM cast pistons, offering superior fatigue resistance for aggressive off-road and dual-sport riding.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eEnhanced Lubrication Design:\u003c\/b\u003e Radial boss machining and specialized oiling slots ensure the wrist pin remains lubricated under intense mechanical stress.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eLow-Friction Skirt Coating:\u003c\/b\u003e Permanent molybdenum disulphide coating protects cylinder walls and reduces internal drag.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eComplete Assembly:\u003c\/b\u003e Kit includes the forged piston, high-performance rings, wrist pin, and pin locks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eExpert Pro-Tip:\u003c\/b\u003e The KTM and Husaberg 450cc engines are renowned for their versatility, but they require precise internal tolerances to stay reliable. Size A is the ideal choice for a cylinder that is still within factory service limits or has been freshly replated. When performing a rebuild with the 8707DA, we recommend a thorough inspection of your cam chain tensioner and oil screens. Always use a fresh top-end gasket kit and premium synthetic oil to provide a professional-grade seal and protect your new forged assembly for miles of reliable adventure.\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\u003e2008-2011\u003c\/td\u003e\n            \u003ctd\u003eKTM\u003c\/td\u003e\n            \u003ctd\u003e450 EXC-R \/ XC-W \/ Six Days \/ Champions Edition\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e2008-2009\u003c\/td\u003e\n            \u003ctd\u003eKTM\u003c\/td\u003e\n            \u003ctd\u003e450 XCR-W\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e2009-2012\u003c\/td\u003e\n            \u003ctd\u003eHusaberg\u003c\/td\u003e\n            \u003ctd\u003eFE 450 \/ FX 450\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 94.95mm piston designed for the standard 95.00mm bore.
