Vortex 254ZG-34 Aluminum Rear Sprocket 520 Pitch 34-Tooth

The Vortex 254ZG-34 is a high-performance 520 pitch, 34-tooth aluminum rear sprocket engineered for serious street and track riders. Manufactured in the USA, this sprocket is precision CNC-machined from aerospace-grade 7075 T6 billet aluminum to deliver an exceptional strength-to-weight ratio over stock steel sprockets.

Reducing rotating mass at the rear wheel directly translates to improved throttle response, sharper acceleration, and more responsive handling — making this sprocket a popular upgrade for both road racing and performance street riding applications.

Key Features:

• 520 pitch — compatible with 520 chain systems and 520 conversion setups
