Vortex 454K-41 Black 41-Tooth 525-Pitch Aluminum Rear Sprocket

The Vortex 454K-41 is a 41-tooth, 525-pitch rear sprocket precision-engineered for performance motorcycle applications. Manufactured in the USA from a specially formulated F5 aluminum alloy developed to Vortex's exact specifications, this sprocket delivers an outstanding combination of low weight and high durability for both street and track use.

The sprocket features a PTFE black hardcoat finish that bonds directly to the aluminum substrate, significantly increasing surface hardness and wear resistance while reducing friction between the chain and sprocket interface. Vortex's patented tooth profile and unique saber-tooth groove design promote smooth, consistent power transfer and extend the service life of both the sprocket and chain.
