This \"Size A\" forged kit is the professional choice for riders performing a top-end refresh on stock 69.00mm bores. At Moto-House MX, we know the KDX220R is a favorite for technical woods riding; Wossner’s aerospace-grade forging provides a massive strength upgrade over the stock cast piston, offering peace of mind and consistent performance through the toughest terrain.\u003c\/p\u003e\n\n\u003cp\u003eThe 8092DA features a dual-ring configuration, which is the ideal setup for the KDX220R's versatile powerband. Unlike single-ring race pistons, the dual-ring design provides superior heat transfer from the piston to the cylinder wall and ensures a better long-term compression seal, perfect for long trail rides and enduro conditions. To ensure a quiet engine and smooth operation, Wossner applies a permanent molybdenum disulphide skirt coating that reduces friction and prevents piston rock. Precision-machined for 69.00mm bores, this 68.94mm piston kit provides the exact tolerances needed to keep your KDX running at its peak.\u003c\/p\u003e\n\n\u003ch3\u003eTop Features: Wossner 8092DA Piston Kit\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eStandard Size A (68.94mm):\u003c\/b\u003e Precision-engineered for stock 69.00mm bores to maintain factory-spec mechanical clearances.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eDual Ring Configuration:\u003c\/b\u003e Provides enhanced cooling and a superior compression seal, making it the perfect choice for the KDX220R’s torque-heavy engine.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eAerospace-Grade Forging:\u003c\/b\u003e Built to be significantly more durable and heat-resilient than the original cast alternatives, reducing the risk of piston failure.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eLow-Friction Skirt Coating:\u003c\/b\u003e Permanent skirt treatment minimizes drag, protects the cylinder wall, and ensures a smoother break-in period.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eOptimized Lightness:\u003c\/b\u003e Precision machining reduces reciprocating mass without compromising the strength of the crown or skirt walls.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eComplete Kit:\u003c\/b\u003e Includes the high-performance forged Size A piston, rings, wrist pin, and circlips.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cb\u003eExpert Pro-Tip:\u003c\/b\u003e The Kawasaki KDX220R is famous for its \"tractable\" power, but that power relies on a perfect top-end seal. If you are refreshing a well-maintained cylinder, the Size A (68.94mm) is the correct starting point to restore that \"like-new\" throttle response. Always use a precision bore gauge to confirm your cylinder measures 69.00mm before installation. For a professional-grade rebuild, always install with a fresh top-end gasket kit and utilize high-quality 2-stroke oil to protect your new forged assembly during the critical break-in hours.\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\u003e1997-2005\u003c\/td\u003e\n            \u003ctd\u003eKawasaki\u003c\/td\u003e\n            \u003ctd\u003eKDX220R\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: Why should I choose a forged piston over a cast one for my KDX?\u003c\/b\u003e\u003cbr\u003e\nA: Forged pistons are created through a high-pressure manufacturing process that results in a denser, stronger material. This makes them far more resistant to the cracks and fatigue that can sometimes affect cast pistons in high-load off-road environments.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eQ: What is the benefit of the dual ring design?\u003c\/b\u003e\u003cbr\u003e\nA: In an enduro-style bike like the KDX220R, two rings help transfer more heat away from the piston and into the cylinder's cooling jackets. This design also provides a longer-lasting seal, which is beneficial for riders who want more time between top-end rebuilds.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eQ: Does this kit include everything I need?\u003c\/b\u003e\u003cbr\u003e\nA: This kit includes the piston, both rings, the wrist pin, and the circlips. We highly recommend purchasing a new small-end wrist pin bearing and a top-end gasket set separately to complete your engine overhaul.\u003c\/p\u003e\n\n\u003ch3\u003eRecommended Pairings\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eComplete Top End Gasket Set:\u003c\/b\u003e Vital for ensuring a leak-free rebuild and maintaining correct engine timing.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cb\u003eHigh-Quality 2-Stroke Premix Oil:\u003c\/b\u003e Keep your new forged piston lubricated and protected during aggressive woods riding.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eRestore your machine’s power and precision today.
