This expertly engineered crankshaft assembly is designed to provide a direct performance upgrade, delivering enhanced torque and horsepower for serious riders.\u003c\/p\u003e\u003ch2\u003eDescription\u003c\/h2\u003e\u003cp\u003eThe Hot Rods 4-Cycle Stroker Crankshaft is meticulously factory assembled and trued to meet or exceed OEM specifications, ensuring exceptional quality and reliability right out of the box. Engineered for a seamless installation, this performance crankshaft often serves as a drop-in replacement, requiring no modifications in most applications. Each unit is precision CNC machined and dynamically balanced to perfectly accommodate the increased stroke, ranging from +2.00 mm to +4.00 mm depending on your specific motorcycle model. This extended stroke directly translates to a larger engine displacement, contributing to substantial horsepower and torque improvements. Constructed from robust 4140 Steel, this crankshaft assembly is built for durability and high-stress environments. It offers excellent compatibility with Cylinder Works Big Bore cylinders, allowing for even more dramatic displacement and horsepower gains, potentially reaching up to 379 cc in optimized setups. While designed for performance, it typically utilizes your stock piston, simplifying the upgrade process.\u003c\/p\u003e\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Engineered Performance:\u003c\/strong\u003e Factory assembled and trued to OEM specifications, ensuring superior quality and a reliable foundation for engine upgrades.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignificant Displacement Increase:\u003c\/strong\u003e Designed to add +2.00 mm to +4.00 mm of stroke, directly boosting engine displacement and unlocking greater horsepower and torque.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeamless Installation:\u003c\/strong\u003e Engineered as a drop-in replacement for many applications, minimizing modification requirements and simplifying the upgrade process.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Balance \u0026amp; Durability:\u003c\/strong\u003e CNC machined and dynamically balanced to perfectly suit the increased stroke, crafted from high-strength 4140 Steel for long-lasting performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBig Bore Compatibility:\u003c\/strong\u003e Perfectly matches with Cylinder Works Big Bore cylinders, offering an ideal pathway to maximize engine displacement and achieve substantial power gains.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Hot Rods\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Stroker\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e 4-Cycle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Crankshaft Assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 4140 Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\/Finish:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke Length:\u003c\/strong\u003e 68.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplacement (Potential):\u003c\/strong\u003e Up to 379 cc (when combined with appropriate cylinders)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e Heavy Duty Crankshaft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVendor Part Number:\u003c\/strong\u003e 4143\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eImportant to Know\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMain bearings are not included and must be purchased separately.\u003c\/li\u003e\n\u003cli\u003eThis crankshaft is not re-buildable as the rods are shorter than OEM specifications.\u003c\/li\u003e\n\u003cli\u003eWhile often a drop-in replacement, some applications may require minor modifications.\u003c\/li\u003e\n\u003cli\u003eTypically uses stock pistons, but verify compatibility for your specific application.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hot Rods","offers":[{"title":"Default Title","offer_id":62384332472650,"sku":"09210997","price":697.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/5b320aad2dc5371b292c468ebc6adc1a.webp?v=1781766899","url":"https:\/\/partsdenmark.com\/fr\/products\/hot-rods-4-cycle-stroker-crankshaft","provider":"Parts Denmark","version":"1.0","type":"link"}
