Vortex 604ZB-49 Black Aluminum Rear Sprocket 49-Tooth

The Vortex 604ZB-49 is a 49-tooth rear sprocket machined from lightweight aerospace-grade aluminum with a durable black hard-coat anodized finish. Designed as a direct-fit replacement or performance upgrade, this sprocket delivers precise power transfer and reduced rotational mass compared to a heavier steel unit.

The black hard-coat anodizing provides enhanced surface hardness for extended wear life, making this sprocket a great choice for both street and track applications. With 49 teeth, this sprocket allows riders to fine-tune their final drive ratio for improved low-end torque and quicker acceleration.
