Specifically engineered for the 2000-2002 Suzuki RM250, this \"Size B\" forged kit is the professional’s choice for riders performing a top-end refresh on a cylinder with several seasons of use. At Moto-House MX, we know that the RM250 is legendary for its sharp handling and aggressive power; Wossner’s aerospace-grade forged construction ensures your engine remains reliable while delivering the crisp throttle response needed to clear the triples.\u003c\/p\u003e\n\n\u003cp\u003eForged from high-performance aluminum alloy, the 8059DB features a dual-ring configuration. This design is highly sought after by 250cc riders for its superior cylinder sealing and improved heat dissipation, ensuring your engine maintains consistent compression even during the final laps of a hot moto. To ensure maximum service life, Wossner applies a permanent molybdenum disulphide skirt coating that reduces friction and prevents piston rock. Precision-machined for 66.41mm bores, this 66.35mm piston kit provides the exact tolerances needed to restore your RM250’s powerband.\u003c\/p\u003e\n\n\u003ch3\u003eTop Features: Wossner 8059DB Piston Kit\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eStandard Size B (66.35mm):\u003c\/b\u003e Precision-machined for 66.41mm bores to compensate for minor cylinder expansion and restore factory-correct clearances.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eDual Ring Configuration:\u003c\/b\u003e Provides an exceptional secondary seal and enhanced cooling, offering a broader and more reliable power delivery across the RPM range.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eAerospace-Grade Forging:\u003c\/b\u003e Significantly stronger and more resilient to thermal stress than OEM cast pistons, ensuring superior durability under racing conditions.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eLow-Friction Skirt Coating:\u003c\/b\u003e Permanent skirt treatment minimizes internal drag, protects the cylinder wall, and ensures a smoother break-in period.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eOptimized Reciprocating Mass:\u003c\/b\u003e Expertly machined to maintain strength in critical areas while remaining lightweight for faster engine acceleration.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eComplete Assembly:\u003c\/b\u003e Includes the high-performance forged Size B piston, dual rings, wrist pin, and circlips.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eExpert Pro-Tip:\u003c\/b\u003e The early 2000s Suzuki RM250 is a favorite among 2-stroke enthusiasts. To keep your engine at peak performance, stepping up to a Wossner Size B (66.35mm) is the standard method to account for the microscopic wear that occurs in used cylinders. Always use a precision bore gauge to confirm your cylinder measures 66.41mm before installation. For a professional-grade rebuild, always install with a fresh top-end gasket kit and utilize premium synthetic 2-stroke oil to protect your forged assembly.\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\u003e2000-2002\u003c\/td\u003e\n            \u003ctd\u003eSuzuki\u003c\/td\u003e\n            \u003ctd\u003eRM250\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 Size B instead of Size A?\u003c\/b\u003e\u003cbr\u003e\nA: Size B (66.35mm) is 0.01mm larger than Size A. It is typically used for a cylinder that has logged significant hours to maintain the tight piston-to-wall clearance necessary for maximum horsepower and to prevent piston slap.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eQ: What is the advantage of a forged piston for my RM250?\u003c\/b\u003e\u003cbr\u003e\nA: Forged pistons are denser and stronger than the original cast pistons. They are much less likely to shatter under extreme stress, making them a vital upgrade for both motocross and off-road racing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eQ: Does this kit include everything needed for the piston change?\u003c\/b\u003e\u003cbr\u003e\nA: Yes, the kit includes the forged piston, the ring set, wrist pin, and pin locks.
