The Dirt Tricks KTM-50-D-B rear sprocket is a 50-tooth, 520-chain sprocket designed for KTM and Husqvarna off-road motorcycles. Manufactured by Dirt Tricks, this black sprocket combines chromoly steel construction with a zirconium coating to provide a durable, lightweight alternative to conventional aluminum and steel sprockets. Its fitment-specific design supports reliable drivetrain performance for motocross, enduro, trail, and other demanding riding applications.
Developed using aerospace-grade steel knowledge, advanced heat-treatment processes, and finite element analysis, the Dirt Tricks rear sprocket is engineered to withstand hard riding and extended use. The minimalist design helps reduce unnecessary weight while maintaining the strength required for high-load off-road conditions. Its zirconium coating reduces friction by up to 50 percent, improves wear resistance, and provides a distinctive black finish.
