Vortex 617ZR-57 Aluminum Rear Sprocket 520 Pitch 57-Tooth Red

The Vortex 617ZR-57 is a 57-tooth, 520-pitch aluminum rear sprocket finished in a striking red anodized color with CNC-machined silver highlights. Designed for performance street and track riders who demand lightweight drivetrain components without sacrificing durability, this sprocket is a direct upgrade over heavy OEM steel units.

Key Features:

• 57-Tooth / 520 Pitch — provides a higher gear ratio for increased low-end torque and acceleration
• CNC machined from 7075-T6 aluminum — exceptional strength-to-weight ratio reduces rotating mass for improved throttle response
• Red anodized finish with machined silver accents — anodized first, then CNC machined for a distinctive two-tone appearance that resists corrosion
• Unique tooth geometry — optimized for smooth chain engagement and release, reducing wear on both chain and sprocket
• 100% manufactured in the USA — precision-machined to tight tolerances for consistent fit and performance
• Fits the 617 sprocket carrier pattern used on select sport and performance motorcycles

Vortex rear sprockets are a trusted choice among racers and performance street riders seeking to fine-tune gear ratios and shed rotational weight. The 617ZR-57 is an ideal choice for riders looking to maximize acceleration and customize their drivetrain setup with a race-proven component.
