The Dirt Tricks KTM-46-D-B Chromoly Rear Sprocket is a 46-tooth, black-finished sprocket designed for KTM, Husqvarna, and GasGas off-road motorcycles using a 520 chain. Developed by Dirt Tricks president and engineer Greg Burns, this rear sprocket combines aerospace-grade steel knowledge, advanced heat treatment, and finite element analysis (FEA) stress analysis to deliver dependable performance in demanding riding conditions.
The Dirt Tricks rear sprocket uses a lightweight minimalist design intended to provide durability comparable to aluminum while offering substantially greater strength and wear resistance. Its chromoly construction is 2.5 times stronger than stainless steel, making it well suited for hard trail riding, motocross, enduro, and other off-road applications. The black finish provides a clean appearance while supporting the sprocket’s durable design.
Designed as a direct-fit replacement for compatible KTM, Husqvarna, and GasGas motorcycles with a 520 drivetrain, the KTM-46-D-B helps maintain proper chain engagement and final-drive performance when installed with a properly matched chain and front sprocket. Dirt Tricks backs its rear sprockets with a two-year guarantee and will replace the sprocket if it wears out during normal use under the terms of the manufacturer’s warranty.
