Vortex 422B-40 Black Steel 40-Tooth Rear Sprocket

The Vortex 422B-40 is a 40-tooth, 422-pitch steel rear sprocket finished in an electro-plated satin black coating to resist corrosion. Built by Vortex Racing — a U.S.-based manufacturer owned and operated by motorcycle racers — this sprocket is engineered to the tightest tolerances using a specially formulated carbon steel alloy that delivers exceptional durability on the street or trail.

Vortex's patented tooth profile sets this sprocket apart from generic alternatives, promoting even chain engagement and extending the working life of both the sprocket and chain. Hardened teeth maintain their geometry mile after mile without compromising the overall strength of the sprocket. Lightening reliefs in the body help reduce rotating mass for improved throttle response and drivetrain efficiency.
