Upgrade your off-road drivetrain with the Dirt Tricks HV-49-Z-C 49-tooth rear sprocket, engineered for demanding enduro and cross-country riding. This Chromatic rear sprocket is manufactured from high-strength chromoly steel with Dirt Tricks’ advanced zirconium coating, providing an excellent balance of low weight, long service life, and reduced friction. The 520 chain configuration is designed for compatible Sherco motorcycles and provides dependable power transfer in challenging riding conditions.
Designed and patented by Dirt Tricks president and engineer Greg Burns, the rear sprocket reflects extensive experience with aerospace steels, heat treatment, and FEA stress analysis. Its minimalist profile helps keep weight comparable to aluminum sprockets while delivering substantially greater durability. Dirt Tricks states that its rear sprockets are 2.5 times stronger than stainless steel, making this model a practical choice for riders who prioritize dependable performance throughout a hard riding season.
The zirconium coating helps reduce friction by up to 50 percent while improving wear resistance and giving the sprocket its distinctive Chromatic appearance. The sprocket is backed by Dirt Tricks’ one-year replacement guarantee if it wears out. The HV-49-Z-C fits 2017–2020 Sherco 250 SC Cross Country, Sherco 300 SC Cross Country, and select 2019–2020 Sherco 450 SC-F Cross Country applications.
