Vortex 527ZRV4-45 ZRV4 Aluminum Rear Sprocket 530 Pitch 45-Tooth

The Vortex 527ZRV4-45 is a 530-pitch, 45-tooth aluminum rear sprocket from Vortex's ZRV4 series, engineered for serious street and track riders who demand lightweight performance without sacrificing durability.

Key Features:

• 100% CNC machined in the USA from a specially formulated aluminum alloy per Vortex specifications
• Black hardcoat PTFE (Polytetrafluoroethylene) finish proven to extend sprocket life by up to 30% compared to standard anodizing
• 530 chain pitch compatible with OEM chain sizes
• 45 teeth for precise gear ratio tuning
• Saber tooth groove design for improved chain engagement and reduced wear
• Cupped construction from the tooth ring down to the body to minimize rotating mass
• Hardened teeth maintain strength over extended mileage
• Stunt sprockets up to 74 teeth available via special order

Reducing rotating mass with an aluminum sprocket versus a heavier OEM steel unit translates directly to improved acceleration response and more agile handling. The ZRV4 series black hardcoat PTFE treatment adds a layer of corrosion resistance and surface hardness, making this sprocket equally at home on the track or daily street riding.
