Designed for the serious enthusiast, this \"Over-Range\" system features an oversized 94mm pulley diameter and re-engineered ramp angles. This allows your drive belt to travel further than the factory variator permits, effectively giving your 2-stroke Minarelli engine a wider gear ratio for explosive take-offs and a significantly higher top-end cruising speed.\u003c\/p\u003e\u003ch3\u003eTechnical Performance Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOversized 94mm Face:\u003c\/strong\u003e Larger diameter than stock variators, providing a greater surface area for the belt to travel higher, resulting in increased top-end velocity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Ramp Geometry:\u003c\/strong\u003e Optimized for use with high-performance sliding weights, allowing for a smoother, more linear power band without the \"dead spots\" common in OEM units.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Tuning Kit:\u003c\/strong\u003e Includes the variator boss, backing plate with sliders, drive face, and precision spacers to ensure perfect alignment and belt tracking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Heat Dissipation:\u003c\/strong\u003e Constructed from a lightweight, high-strength alloy designed to maintain consistent friction levels and prevent belt slip during aggressive riding.\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003ch3\u003eComprehensive Fitment Guide\u003c\/h3\u003e\u003cp\u003eThis 13mm spline variator is designed for \u003cstrong\u003e50cc 2-Stroke Minarelli (1PE40QMB\/Jog)\u003c\/strong\u003e engines:\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"text-align: left;\"\u003eBrand \/ Engine\u003c\/th\u003e\n\u003cth style=\"text-align: left;\"\u003eCompatible Model Series\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eYamaha\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eZuma 50 (Pre-2012), Jog 50, Vino 50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAdly \/ Hammerhead\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFox 50, Jet 50, Muddy Bug 50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCrank Specs\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFits \u003cstrong\u003e13mm\u003c\/strong\u003e Crankshaft \/ 17-Tooth Spline\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003chr\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePulley Outer Diameter:\u003c\/strong\u003e 94mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter (Boss):\u003c\/strong\u003e 18mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrankshaft Spline:\u003c\/strong\u003e 13mm (17-Tooth)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Includes:\u003c\/strong\u003e Variator, Drive Face, Back Plate, Sliders, and Spacers\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003cblockquote\u003e\n\u003cstrong\u003eMechanic's Note:\u003c\/strong\u003e This is an \"Over-Range\" kit, meaning it is physically larger than your stock variator.\u003c\/blockquote\u003e\u003cblockquote\u003e\n\u003cstrong\u003eInstallation Tip:\u003c\/strong\u003e Because of the 94mm diameter, ensure your \u003cstrong\u003eStarter Bendix\u003c\/strong\u003e and crankcase have enough clearance; some minor material removal from the case may be required on specific clones.\u003c\/blockquote\u003e\u003cblockquote\u003e\n\u003cstrong\u003ePro Tip:\u003c\/strong\u003e To get the most out of this kit, pair it with \u003cstrong\u003e\u003ca href=\"https:\/\/www.scooterworks.com\"\u003eDr. Pulley Sliding Weights\u003c\/a\u003e\u003c\/strong\u003e and a fresh \u003cstrong\u003e\u003ca href=\"https:\/\/www.scooterworks.com\"\u003eKevlar Drive Belt\u003c\/a\u003e\u003c\/strong\u003e to handle the increased gear range!\u003c\/blockquote\u003e\u003cp style=\"font-size: 0.85em; color: #666;\"\u003e\u003cstrong\u003eSKU:\u003c\/strong\u003e 1200-1111 \u003cbr\u003e\u003cstrong\u003eVendor:\u003c\/strong\u003e Dr. Pulley\u003c\/p\u003e","brand":"Dr. Pulley","offers":[{"title":"Default Title","offer_id":46756792041752,"sku":"1200-1184","price":102.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0782\/1728\/1816\/products\/1200-1184_cec4d658-8b8b-4bc5-a561-9c2c272a4609.jpg?v=1695271956"},{"product_id":"dr-pulley-over-range-variator-yamaha-jog-90-2t-1200-1185","title":"Dr. Pulley Over-range Variator; Yamaha Jog 90 2T","description":"High Quality, High Performance variator from Dr. Pulley.
