Engineered specifically for the classic Polaris 250cc 2-stroke engines found in the Trail Blazer, Trail Boss, and Scrambler models, this +1.00mm oversize forged kit is the professional choice for cylinders that require significant boring to remove deep scoring or heavy wear. At Moto-House MX, we know these machines are built to last; upgrading to a Wossner forged piston provides superior structural integrity compared to stock cast pistons, ensuring your ATV remains reliable on the farm or the trail.\u003c\/p\u003e\n\n\u003cp\u003eThe 8094D100 features a dual-ring configuration, designed to provide maximum heat transfer and a consistent compression seal for utility and recreational riding. This setup is ideal for air-cooled and liquid-cooled 250cc Polaris engines that operate under heavy loads. To ensure a quiet, smooth-running engine, Wossner applies a permanent molybdenum disulphide skirt coating that reduces friction and prevents piston rock. Precision-machined for a 73.00mm finished bore, this 72.93mm piston kit is the ultimate way to refresh your high-hour Polaris engine.\u003c\/p\u003e\n\n\u003ch3\u003eTop Features: Wossner 8094D100 Piston Kit\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003e+1.00mm Oversize (72.93mm):\u003c\/b\u003e Designed for cylinders that need to be bored out to a 73.00mm finished size to restore a perfect, round bore.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eDual Ring Configuration:\u003c\/b\u003e Enhances cooling and provides a more durable compression seal, perfect for the demands of off-road ATV use.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eAerospace-Grade Forging:\u003c\/b\u003e Offers significantly higher strength and heat resistance than traditional cast pistons, reducing the risk of failure.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eLow-Friction Skirt Coating:\u003c\/b\u003e Permanent skirt treatment minimizes drag, protects the cylinder walls, and ensures a smoother break-in period.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eOptimized Machining:\u003c\/b\u003e Precisely engineered to balance lightness with the necessary strength in the crown and skirt wall cross-sections.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eComplete Kit:\u003c\/b\u003e Includes the high-performance forged +1.00mm piston, rings, wrist pin, and circlips.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eExpert Pro-Tip:\u003c\/b\u003e Moving to a +1.00mm oversize is a great way to save a cylinder that has seen heavy use. It is critical that your cylinder is precision-bored and honed by a professional machine shop to exactly 73.00mm to achieve the correct piston-to-wall clearance. For a professional-grade rebuild, always install with a fresh top-end gasket kit and utilize premium 2-stroke oil to protect your new forged assembly during the initial break-in cycles.\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\u003e1990-2005\u003c\/td\u003e\n\u003ctd\u003ePolaris\u003c\/td\u003e\n\u003ctd\u003eTrail Blazer 250 \/ ES \/ Freedom\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003e1985-1999\u003c\/td\u003e\n\u003ctd\u003ePolaris\u003c\/td\u003e\n\u003ctd\u003eTrail Boss 250 \/ 2x4 \/ 4x4 \/ ES \/ R\u003c\/td\u003e\n\u003c\/tr\u003e\n        \u003ctr\u003e\n\u003ctd\u003e1985-1986\u003c\/td\u003e\n\u003ctd\u003ePolaris\u003c\/td\u003e\n\u003ctd\u003eScrambler 250 \/ 250R ES\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: When should I use a +1.00mm oversize piston?\u003c\/b\u003e\u003cbr\u003e\nA: This piston is used when your cylinder bore has damage or wear that cannot be cleaned up by a smaller oversize (like +0.50mm). It allows you to bore the cylinder to 73.00mm and restore like-new performance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eQ: Are forged pistons better for older Polaris ATVs?\u003c\/b\u003e\u003cbr\u003e\nA: Absolutely. Forged pistons are much stronger and more resistant to heat-induced fatigue than cast pistons, making them an excellent choice for air-cooled engines or utility machines that work hard.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eQ: Does this kit include everything I need?\u003c\/b\u003e\u003cbr\u003e\nA: The kit includes the forged piston, dual rings, wrist pin, and circlips.
