Engineered for the 1985-2001 Honda CR500R, this Standard Size A kit is the definitive choice for riders looking to restore Factory Quality compression and performance to their original bore. At Moto-House MX, we provide the heavy-duty forged components required to handle the massive torque and explosive power of the ultimate open-class 2-stroke.\u003c\/p\u003e\n\n\u003cp\u003eForged from aerospace-grade aluminum alloy, this piston is built to withstand the extreme mechanical loads of a 500cc single. Unlike cast pistons, Wossner’s forged design offers superior thermal stability and structural strength, which is vital for an engine known for its significant vibration and heat. The permanent skirt coating reduces friction and piston rock, resulting in a quieter engine and smoother operation. Optimized machining keeps the reciprocating mass as low as possible while reinforcing the crown for maximum durability.\u003c\/p\u003e\n\n\u003ch3\u003eTop Features: Wossner 8229DA Piston Kit\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eStandard Size A (88.92mm Piston):\u003c\/b\u003e Precision-engineered for standard 89.00mm bores to restore peak performance to your Honda 500.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eAerospace Forged Alloy:\u003c\/b\u003e Maximum structural integrity to handle the extreme cylinder pressures of the CR500 engine.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eLow-Friction Skirt Coating:\u003c\/b\u003e Permanent coating minimizes wear and noise, essential for the large-bore 500cc piston.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eSingle-Ring Performance:\u003c\/b\u003e Optimized for reduced drag and efficient power delivery across the broad CR500 powerband.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eComplete Kit:\u003c\/b\u003e Includes everything needed for a top-end refresh: forged piston, ring, wrist pin, and clips.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eExpert Pro-Tip:\u003c\/b\u003e Rebuilding a CR500R requires extreme attention to detail due to its massive displacement. When installing this Standard Size A kit, ensure your cylinder bore is within factory service limits and free of glazing.

If your cylinder has been bored over, you will need an oversize kit.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eQ: Does this kit include the wrist pin bearing?\u003c\/b\u003e\u003cbr\u003e\nA: No, the kit includes the piston, ring, pin, and clips. Because of the heavy loads on a CR500 small-end bearing, we strongly recommend purchasing a new high-quality bearing separately.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eQ: Why choose a forged piston for a CR500?\u003c\/b\u003e\u003cbr\u003e\nA: The CR500 generates significant heat and vibration. A forged piston is much stronger than a cast one, making it far more resistant to fatigue-related failure in such a high-output large-bore engine.\u003c\/p\u003e\n\n\u003ch3\u003eRecommended Pairings\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eTop End Gasket Kit:\u003c\/b\u003e Essential for a professional, leak-free engine rebuild.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eMotorex Cross Power 2T Oil:\u003c\/b\u003e Premium synthetic protection specifically formulated for high-performance 2-strokes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eRestore your Honda’s legendary power today.
