Vortex 454-47 Silver 47-Tooth 525-Pitch Rear Sprocket

The Vortex 454-47 is a lightweight aluminum rear sprocket engineered to the exacting standards of one of America's most trusted motorcycle racing component manufacturers. Machined from 7075 T6 billet aluminum, this sprocket delivers an exceptional strength-to-weight ratio that makes it a go-to upgrade over heavy stock steel sprockets.

Reducing rotating mass at the rear wheel has a multiplying effect on overall drivetrain performance — less rotational weight means improved throttle response and quicker acceleration. Vortex's patented tooth profile is precision-CNC machined with saber tooth grooves for reduced friction, smoother chain engagement, and extended sprocket life.
