The Vortex 527ZB-37 CAT5 Rear Aluminum Sprocket is a lightweight, race-proven rear sprocket machined from high-grade aluminum and finished in a vibrant blue anodize. Designed for 527 chain pitch applications with a 37-tooth count, this sprocket delivers the precision and durability that Vortex is known for in both street and competition environments.

Key Features:

• CNC machined from 7075 aluminum — specially formulated alloy per Vortex specifications for maximum strength-to-weight ratio
• Anodized first, then CNC machined — produces a vibrant blue color with bright silver machined highlights on the teeth and sweep areas
• Patented CAT5 tooth design — saber tooth grooves and unique tooth geometry increase sprocket longevity and improve chain engagement
• 37-tooth rear sprocket — optimized tooth count for a range of performance applications
• 527 chain pitch — designed as a direct OEM replacement or for 527 chain conversions
• Lightweight construction reduces unsprung rotational mass for improved acceleration and handling response
• Trusted by professional racers and serious street riders worldwide

The Vortex CAT5 series uses a patented sprocket design unlike any other on the market. The anodizing process is completed before CNC machining, resulting in a trick two-tone appearance with a bold blue body and polished silver tooth faces. This sprocket is a direct bolt-on replacement that upgrades both the performance and aesthetics of your motorcycle's drivetrain.
