The Dirt Tricks CR-50-Z-C Chromatic Rear Sprocket is a 50-tooth, 520-chain sprocket engineered for demanding off-road riding. Designed and patented by Dirt Tricks president and engineer Greg Burns, this sprocket reflects extensive expertise in aerospace steels, advanced heat treatments, and finite element analysis (FEA). Its chromoly steel and zirconium construction delivers high strength and long service life without the excessive weight associated with conventional steel sprockets.
Feature: The Zirconium coating reduces friction by up to 50%, helps improve durability, and provides the distinctive Chromatic finish. The minimalist design delivers a clean appearance while maintaining the strength required for hard riding. Dirt Tricks Rear Sprockets are engineered to be 2.5 times stronger than stainless steel and are backed by a one-year guarantee; if the sprocket wears out during the coverage period, Dirt Tricks will replace it.
The Dirt Tricks CR-50-Z-C fits select Honda motorcycles, including the 2017 Honda CRF450RX and Honda CR500R models from 1984 through 1988 and 1998 through 2001. Verify the motorcycle model, year, chain size, tooth count, and mounting pattern before installation.
