Vortex 452AZKV4-49 CAT5 Aluminum Rear Sprocket 49-Tooth 520-Pitch

The Vortex 452AZKV4-49 is a 49-tooth, 520-pitch CAT5 series aluminum rear sprocket built for motorcycle road racing, track days, and high-performance street riding. Vortex CAT5 series rear sprockets are anodized in color first, then CNC machined from 7075 aluminum, producing a trick colored sprocket with silver highlights.
