Engineered for exceptional durability and performance, this high-quality kit provides everything needed for a robust engine rebuild or upgrade, ensuring your motorcycle operates at its peak.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Wossner Pro Series \u003cstrong\u003e250cc 4-stroke piston kit\u003c\/strong\u003e is meticulously crafted from aerospace-grade forged aluminum alloy, offering superior strength and longevity compared to cast alternatives. Each piston features an optimized design with precision machining, achieving an ideal balance of lightness for reduced reciprocating mass and maintained strength in critical areas like the crown and skirt wall cross-section. This results in improved throttle response and higher RPM capabilities without compromising reliability. A key performance advantage is the advanced Molybdenum Disulphite (Moly) skirt coating, a permanent application that significantly reduces friction and minimizes piston rock. This not only contributes to quieter operation but also enhances overall engine efficiency and extends the lifespan of both the piston and cylinder. With a precise 74.95 mm piston diameter designed for a 75.00 mm bore and an aggressive 12.8:1 compression ratio, this Wossner forged piston kit is built to deliver race-proven power and consistent performance for demanding riders.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAerospace-Grade Forged Aluminum:\u003c\/strong\u003e Constructed from premium forged aluminum alloy for unmatched strength, durability, and resilience under extreme engine conditions.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAdvanced Molybdenum Disulphite Skirt Coating:\u003c\/strong\u003e Features a permanent Moly coating on the skirt to drastically reduce friction, minimize piston rock, and ensure quieter, more efficient engine operation.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOptimized Lightweight Design:\u003c\/strong\u003e Precision machining balances reduced weight for improved acceleration and responsiveness with reinforced strength in critical stress areas.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComplete Engine Rebuild Kit:\u003c\/strong\u003e Each Wossner \u003cstrong\u003emotorcycle piston kit\u003c\/strong\u003e includes the high-performance piston, nitride-coated steel rings, piston pin, and retaining clips, providing all necessary components for a comprehensive rebuild.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh Compression Performance:\u003c\/strong\u003e Engineered with a 12.8:1 compression ratio to maximize power output and engine efficiency, perfect for performance-oriented 4-stroke applications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eBrand: Wossner\u003c\/li\u003e\n    \u003cli\u003eModel: Pro Series\u003c\/li\u003e\n    \u003cli\u003eProduct Name: Piston Kit\u003c\/li\u003e\n    \u003cli\u003eEngine Type: 4-Stroke\u003c\/li\u003e\n    \u003cli\u003eDisplacement: 250 cc\u003c\/li\u003e\n    \u003cli\u003ePiston Material: Forged Aluminum Alloy\u003c\/li\u003e\n    \u003cli\u003ePiston Diameter: 74.95 mm\u003c\/li\u003e\n    \u003cli\u003eBore Size: 75.00 mm\u003c\/li\u003e\n    \u003cli\u003eCompression Ratio: 12.8:1\u003c\/li\u003e\n    \u003cli\u003eSkirt Coating: Molybdenum Disulphite\u003c\/li\u003e\n    \u003cli\u003eRing Material: Nitride Coated Steel, Cast\u003c\/li\u003e\n    \u003cli\u003ePiston Size: Standard Size A\u003c\/li\u003e\n    \u003cli\u003eKit Includes: Piston, Rings, Pin, Clips\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wossner","offers":[{"title":"Default Title","offer_id":62381566493002,"sku":"09107061","price":924.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/98e46390bd48eeeca6d48b4b396326c8_dad79cb1-d62a-4e40-8c05-1be30c78c76c.webp?v=1781742511","url":"https:\/\/partsdenmark.pl\/products\/wossner-pro-series-piston-kit-for-250cc-4-stroke-engines","provider":"Parts Denmark","version":"1.0","type":"link"}
