BikeMaster Arctic Cat Rear Steel Sprocket 520 40T - Black

This is a BikeMaster 520 pitch, 40-tooth rear steel sprocket in black. It's built from 1045 steel, a solid material for drivetrain components that need to hold up to the demands of riding. The black Cataphoresis finish not only looks good but also helps protect the steel.

This sprocket is designed to work with 520 pitch chains and is a direct fit for a range of ATVs, including models like the Arctic Cat DVX 400, Kawasaki KFX400, and Suzuki LT-Z400 QuadSport Z. The 40-tooth count is a common choice for balancing acceleration and top-end speed, depending on your riding style and the specific ATV. BikeMaster machines these sprockets for smooth power delivery and good engagement with your chain.

It's a well-made replacement part that should give you reliable performance. Consider pairing it with a compatible BikeMaster chain for optimal results.
