Specifically engineered for the Beta 300cc 2-stroke platform, including the 300 RR, Race Edition, X-Pro, and Xtrainer (2022-2026), the \"Size C\" piston is the professional solution for engines that have seen heavy use. At Moto-House MX, we know that after many hours on the trail, 300cc cylinders can expand; this +0.02mm Size C kit provides the precise fitment needed to eliminate piston rock and restore the legendary low-end torque Beta is known for.\u003c\/p\u003e\n\n\u003cp\u003eForged from high-performance aerospace aluminum alloy, the 8324DC offers superior structural integrity for the most demanding hard enduro conditions. This kit features a dual-ring configuration, which provides an exceptional secondary seal and better heat dissipation—vital for keeping your engine cool during technical climbs. To ensure maximum service life, Wossner applies a permanent molybdenum disulphide skirt coating that reduces friction and protects the cylinder wall. This 72.97mm piston is precision-matched for 73.02mm bores, allowing you to maximize the life of your Beta cylinder before requiring a costly replate.\u003c\/p\u003e\n\n\u003ch3\u003eTop Features: Wossner 8324DC Piston Kit\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eStandard Size C (72.97mm):\u003c\/b\u003e Specifically designed for 73.02mm bores, providing a tighter fit for cylinders with moderate wear to restore peak compression.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eDual Ring Design:\u003c\/b\u003e Optimizes cylinder sealing and heat transfer for consistent power delivery under high-load off-road conditions.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eAerospace-Grade Forged Construction:\u003c\/b\u003e Significantly stronger and more resilient than stock cast pistons, offering maximum fatigue resistance.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eLow-Friction Skirt Coating:\u003c\/b\u003e Permanent skirt treatment reduces internal drag and ensures a smooth break-in and quieter operation.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eLightweight Machining:\u003c\/b\u003e Optimized for weight reduction without sacrificing strength in the crown or skirt wall, maintaining snappy throttle response.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eComplete Assembly:\u003c\/b\u003e Kit includes the forged Size C piston, performance rings, wrist pin, and pin clips.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eExpert Pro-Tip:\u003c\/b\u003e When your Beta 300 cylinder has seen significant trail time and measures slightly larger than the original spec, moving to a Wossner Size C (72.97mm) is the expert way to restore perfect piston-to-wall clearance. Always use a precision bore gauge to confirm your cylinder measures 73.02mm before installation. For a professional-grade rebuild, always install with a fresh top-end gasket kit and utilize premium 2-stroke oil to protect your investment.\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\u003e2022-2024\u003c\/td\u003e\n            \u003ctd\u003eBeta\u003c\/td\u003e\n            \u003ctd\u003e300 RR\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e2022-2025\u003c\/td\u003e\n            \u003ctd\u003eBeta\u003c\/td\u003e\n            \u003ctd\u003e300 RR - Race Edition\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e2025-2026\u003c\/td\u003e\n            \u003ctd\u003eBeta\u003c\/td\u003e\n            \u003ctd\u003e300 RR X-Pro\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e2022-2025\u003c\/td\u003e\n            \u003ctd\u003eBeta\u003c\/td\u003e\n            \u003ctd\u003e300 Xtrainer\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 choose a Size C piston?\u003c\/b\u003e\u003cbr\u003e\nA: You should move to a Size C (72.97mm) when your cylinder has worn beyond the specifications for Size A or B.
