The Dirt Tricks KTM-48-RAW Rear Sprocket is a 48-tooth chromoly replacement sprocket designed for off-road motorcycles using a 520 chain. Built by Dirt Tricks with advanced aerospace-steel knowledge, specialized heat treatment, and finite element analysis, this sprocket delivers dependable strength and long service life for demanding riding conditions. The raw finish provides a clean, functional appearance while supporting the sprocket’s rugged performance.
Developed by Dirt Tricks president and engineer Greg Burns, the design targets season-long durability without the excess weight commonly associated with heavy-duty steel sprockets. Its minimalist construction helps maintain a competitive weight comparable to aluminum while offering substantially greater wear resistance. The KTM-48-RAW is engineered for riders who need consistent power transfer and reliable performance across hard off-road use, including compatible KTM, GasGas, Husqvarna, and Sherco applications when matched to the motorcycle’s required mounting pattern and gearing specifications.
Fitment: This 48-tooth rear sprocket is intended for motorcycles equipped for a 520 chain and compatible rear hub mounting. Confirm the motorcycle model, year, chain size, bolt pattern, and desired final-drive ratio before installation. Dirt Tricks backs its rear sprockets with a two-year guarantee and will replace the sprocket if it wears out under the terms of the manufacturer’s warranty.
