The Dirt Tricks KTM85-47-Z-C rear sprocket is a 47-tooth zirconium-coated chromoly steel replacement designed for select KTM 85 SX and Husqvarna TC 85 motorcycles using a 428 chain. Developed by Dirt Tricks president and engineer Greg Burns, this sprocket reflects extensive experience with aerospace steels, advanced heat treatments, and finite element analysis. Its minimalist design delivers a strong, lightweight solution for demanding off-road riding.
The zirconium coating helps reduce friction by up to 50 percent while improving durability and providing the distinctive Chromatic finish. Dirt Tricks rear sprockets are engineered to be 2.5 times stronger than stainless steel, offering reliable performance through hard riding and extended use. The KTM85-47-Z-C is backed by Dirt Tricks’ two-year guarantee; if normal riding wears out the sprocket during that period, Dirt Tricks will replace it.
Fitment includes the 2017 Husqvarna TC 85 (17/14) and 2004–2012 KTM 85 SX (17/14). Verify the motorcycle model, wheel configuration, chain size, and required tooth count before installation. This product is manufactured by Dirt Tricks and is identified by manufacturer part number KTM85-47-Z-C and vendor part number KTM85-47-Z-C.
