Upgrade the final drive of your off-road motorcycle with the Dirt Tricks 51-Tooth 520 Chromatic Zirconium Rear Sprocket, manufacturer part number HV-51-Z-C. 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.
The 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.
This 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.
