Vortex 642AZK-48 CAT5 530 Aluminum Rear Sprocket 48-Tooth Black

The Vortex 642AZK-48 is a CAT5 series aluminum rear sprocket featuring a 530 chain pitch and 48-tooth count in a striking black anodized finish. Engineered for motorcycle road and track use, this sprocket is the choice of performance riders who demand both lightweight construction and visual appeal.

CAT5 Finish: The CAT5 series is anodized in color first, then CNC machined from 7075 aerospace-grade aluminum, producing a trick black-finished sprocket with contrasting bright silver highlights on the sweeps, mud grooves, and tooth faces.

Key Features:

• 530 Chain Pitch — 48-tooth rear sprocket for 530-series chain applications
• 7075 Aerospace-Grade Aluminum — lightweight construction reduces rotating mass for improved acceleration response
• 100% CNC Manufactured in the U.S.A. — machined to the tightest tolerances for precise fit and concentricity
