The Dirt Tricks KTM85-46-Z-C rear sprocket is a 46-tooth replacement sprocket designed for select KTM 85 SX and Husqvarna TC 85 motorcycles using a 428 chain. Manufactured by Dirt Tricks, this Chromatic zirconium sprocket combines lightweight construction with the strength and durability required for demanding off-road riding. Its minimalist design provides dependable performance without the excessive weight commonly associated with heavy-duty steel sprockets.
Developed by Dirt Tricks president and engineer Greg Burns, the sprocket design incorporates aerospace-grade steel knowledge, advanced heat treatment, and finite element analysis for improved stress management. The zirconium coating helps reduce friction by up to 50 percent, supports extended service life, and provides a distinctive finish. Dirt Tricks states that its rear sprockets are 2.5 times stronger than stainless steel and backs them with a two-year guarantee against wear.
Fitment includes the 2017 Husqvarna TC 85 in the 17/14 configuration and 2004-2012 KTM 85 SX models in the 17/14 configuration.
