The Dirt Tricks KTM-48-Z-C Chromatic Zirconium Rear Sprocket is a 48-tooth replacement sprocket designed for KTM and Husqvarna off-road motorcycles using a 520 chain. Manufactured by Dirt Tricks, this sprocket combines chromoly steel engineering with a lightweight zirconium construction to deliver reliable performance for demanding trail, motocross, and hard-riding applications. Its fitment-specific design supports proper chain engagement and dependable power transfer when replacing a worn or damaged rear sprocket.
Designed and patented by Dirt Tricks president and engineer Greg Burns, the sprocket reflects expertise in aerospace steels, advanced heat treatments, and finite element analysis. The minimalist profile helps reduce weight while maintaining the strength required for aggressive off-road use. Dirt Tricks states that its rear sprockets are 2.5 times stronger than stainless steel, providing a durable alternative to conventional aluminum and steel sprockets.
The Chromatic finish provides a distinctive appearance, while the zirconium coating is engineered to reduce friction by up to 50 percent and improve wear resistance. Dirt Tricks backs its rear sprockets with a two-year guarantee, including replacement if the sprocket wears out during normal use. Verify the motorcycle model, chain size, mounting pattern, and required tooth count before installation to ensure compatibility. Manufacturer and vendor part number: KTM-48-Z-C.
