Designed by Dirt Tricks president and engineer Greg Burns, this rear sprocket reflects extensive knowledge of aerospace steels, heat treatment, and finite element analysis. Its lightweight minimalist design delivers the strength and durability needed for demanding trail, enduro, and cross-country riding.\u003c\/p\u003e\u003cp\u003eThe Zirconium construction is lighter than comparable twin-metal sprocket designs, while the specialized coating helps reduce friction by up to 50 percent and improves wear resistance. Dirt Tricks rear sprockets are engineered to be 2.5 times stronger than stainless steel, providing long service life without the typical weight penalty associated with highly durable steel components. The Chromatic finish also adds a distinctive appearance to your motorcycle.\u003c\/p\u003e\u003cp\u003eThis 51-tooth sprocket uses a 520 chain size and is designed for fitment on select Sherco motorcycles, including the 2017-2020 Sherco 250 SC Cross Country, 2017-2020 Sherco 300 SC Cross Country, and 2019-2020 Sherco 450 SC-F Cross Country. Confirm the motorcycle model, year, chain size, and existing sprocket configuration before installation. Dirt Tricks backs this rear sprocket with a one-year guarantee: if normal hard riding wears it out during that period, it will be replaced.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e51-tooth rear sprocket for 520 chain applications\u003c\/li\u003e\n\u003cli\u003eDirt Tricks Zirconium construction provides a lightweight alternative to twin-metal designs\u003c\/li\u003e\n\u003cli\u003eChromatic coating reduces friction by up to 50 percent and improves durability\u003c\/li\u003e\n\u003cli\u003eEngineered to be 2.5 times stronger than stainless steel\u003c\/li\u003e\n\u003cli\u003eMinimalist design balances strength, service life, and weight\u003c\/li\u003e\n\u003cli\u003eDesigned for select 2017-2020 Sherco 250 SC, 300 SC, and 2019-2020 450 SC-F Cross Country models\u003c\/li\u003e\n\u003cli\u003eBrand: Dirt Tricks\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: HV-51-Z-C\u003c\/li\u003e\n\u003cli\u003eVendor part number: 254-170151\u003c\/li\u003e\n\u003cli\u003eBacked by a one-year wear guarantee from Dirt Tricks\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\n2017 Sherco 250 SC Cross Country\u003cbr\u003e\n2017 Sherco 300 SC Cross Country\u003cbr\u003e\n2018 Sherco 250 SC Cross Country\u003cbr\u003e\n2018 Sherco 300 SC Cross Country\u003cbr\u003e\n2019 Sherco 250 SC Cross Country\u003cbr\u003e\n2019 Sherco 300 SC Cross Country\u003cbr\u003e\n2019 Sherco 450 SC-F Cross Country\u003cbr\u003e\n2020 Sherco 250 SC Cross Country\u003cbr\u003e\n2020 Sherco 300 SC Cross Country\u003cbr\u003e\n2020 Sherco 450 SC-F Cross Country","brand":"DIRT TRICKS","offers":[{"title":"Default Title","offer_id":67551222071531,"sku":"254-170151","price":139.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/dc6e-6165d1f6119e3_ea1a1be7-f2f1-4ad7-9c7a-c02eb8466fba.jpg?v=1790716193","url":"https:\/\/ctracingservices.com\/products\/dirt-tricks-51-tooth-520-chromatic-zirconium-rear-sprocket-part-number-hv-51-z-c","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
