The Dirt Tricks CR2-12 Front Countershaft Sprocket is a 12-tooth tool steel sprocket designed for Honda motorcycles using a 520 chain. Developed by Dirt Tricks president and engineer Greg Burns, this sprocket reflects extensive experience with aerospace steels, advanced heat treatments, and FEA stress analysis. Its durable construction is engineered for demanding off-road use and long service life.
Featuring Dirt Tricks' minimalist sprocket design, the CR2-12 provides a strong, lightweight alternative to conventional sprockets. Dirt Tricks sprockets are engineered to be 2.5 times stronger than stainless steel, helping resist wear during hard riding. The sprocket is backed by Dirt Tricks' one-year guarantee: if normal riding wears it out during the warranty period, Dirt Tricks will replace it.
This Dirt Tricks front countershaft sprocket fits the 2017 Honda CRF450RX and Honda CR500R models from 1984 through 1988 and from 1998 through 2001. Verify the motorcycle model, year, chain size, tooth count, and manufacturer part number before installation. The manufacturer part number is CR2-12, and the vendor part number is 254-12012.
