Vortex 526AZOV4-40 CAT5 Aluminum Rear Sprocket 520 Chain 40-Tooth Anodized

The Vortex 526AZOV4-40 is a 40-tooth, 520-pitch anodized aluminum rear sprocket built for street and racing applications. Machined from 7075-T6 billet aluminum, this lightweight sprocket reduces rotating mass for improved throttle response, acceleration, and directional changes.

Key Features:

• 7075-T6 billet aluminum construction — exceptional strength-to-weight ratio
• 520 chain pitch — compatible with 520 chain drive systems
• 40-tooth rear sprocket — optimized for balanced street and sport riding gearing
• Anodized finish with CNC-machined silver highlights — creates a striking two-tone appearance
• Saber tooth groove design — Vortex patented tooth profile increases sprocket longevity
• PTFE-bonded hardcoat surface on anodized models bonds to aluminum for reduced friction and enhanced durability
• 100% CNC manufactured in the U.S.A.
• Vortex patent-pending sprocket design

The 526 series is the standard-bearer in motorcycle racing sprockets, trusted by riders at every level from weekend track days to professional competition. The anodized OV4 finish is applied before CNC machining, resulting in a vibrant color body with bright silver accent cuts.
