Vortex 438ZB-41 CAT5 Rear Aluminum Sprocket 530 Pitch 41-Tooth Blue

The Vortex 438ZB-41 CAT5 Rear Aluminum Sprocket is a high-performance, 41-tooth, 530-pitch rear sprocket built for motorcycle riders who demand precision, durability, and a sharp look. Machined from aerospace-grade 7075 T6 aluminum and finished with a vibrant blue anodize, this sprocket delivers a significant weight reduction over stock steel sprockets — reducing rotating mass for improved throttle response and acceleration.

The CAT5 series uses a unique color-first anodizing process: the sprocket is anodized blue before CNC machining, revealing bright silver highlights on the tooth faces and machined surfaces. The result is a striking, two-tone appearance that holds up under hard use.

Key Features:

• 530 Pitch — 41 teeth, rear sprocket placement
• 7075 T6 billet aluminum construction — lightweight and highly durable
• 100% CNC machined in the U.S.A. to the tightest tolerances
• Saber tooth groove design — patented Vortex tooth profile increases longevity and reduces chain wear
• Blue anodized finish with contrasting silver CNC-machined highlights
• Specially formulated alloy per Vortex Racing specifications
• Reduces rotating mass for improved acceleration and power transfer
• Perfectly concentric sprocket profile for smooth, vibration-free operation

The Vortex CAT5 sprocket is a trusted choice among road racers and performance street riders. Its tight manufacturing tolerances ensure consistent chain engagement, extended drivetrain life, and a factory-quality fit. MPN: 438ZB-41.
