Most camshaft designs are developed only on a dyno. Good camshaft designs not only increase power, they also improve throttle response. However, more power and better throttle response is a difficult design problem. Hotcams’ ITR technology solved this dilemma through highly engineered opening ramps not found on other cams. Using ITR technology, the critical ramp area is designed to give your engine a cleaner intake charge and a more efficient combustion cycle, making your engine more responsive at all throttle openings and giving the rider better feel and control of the engine! You will notice the difference!\n\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eUpgrade your Yamaha YZ450F with the Hot Cams Racing Cam Stage 2 (Part Number 4281-2E). Designed for offroad enthusiasts seeking enhanced engine responsiveness, this high-performance camshaft features advanced ITR technology that optimizes intake charge and combustion efficiency. The result is a noticeable increase in throttle response and overall power output, providing a more responsive and controlled riding experience. This camshaft is engineered to work with stock valve springs and rockers in most applications, making installation straightforward without requiring a core. Additionally, adjustable cam sprockets are included with some models, allowing fine-tuning for optimal performance. Built for race use only in California, this camshaft is not legal for street use on pollution-controlled vehicles, but a waiver is available for race applications. Whether you’re racing or riding aggressively, the Hot Cams Stage 2 camshaft is designed to maximize your Yamaha YZ450F’s engine potential, delivering improved power delivery and throttle feel across all RPM ranges.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eHigh performance racing camshaft designed for offroad use\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eNo core required for easy installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with stock valve springs and rockers in most applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable cam sprockets included with some models for precise tuning\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnhanced throttle response through innovative ITR technology\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for race use only in California; waiver available\u003c\/li\u003e\u003c\/ul\u003e\n\n\u003cp\u003eProduct Type: Engine\n\u003cbr\u003eSegment: Offroad\n\u003cbr\u003eDivision: Engine\n\u003cbr\u003eClass: Camshafts \u0026amp; Components\n\u003cbr\u003eSub Class: Camshafts\u003c\/p\u003e\n\n\u003cp\u003eFITMENT:\n\u003cbr\u003e2014 Yamaha YZ450F\n\u003cbr\u003e2015 Yamaha YZ450F\u003c\/p\u003e","brand":"HOT CAMS","offers":[{"title":"Default Title","offer_id":47676755968157,"sku":"68-2279","price":330.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0742\/9242\/8957\/files\/bf25-572a800173e23.jpg?v=1771986337","url":"https:\/\/thepartjungle.com\/products\/hot-cams-racing-cam-stage-2-for-yamaha-yz450f-improved-throttle-response-and-performance","provider":"The Part Jungle","version":"1.0","type":"link"}
