Vortex 491ZR-48 48-Tooth 520-Pitch Aluminum Rear Sprocket Red

The Vortex 491ZR-48 is a lightweight aluminum rear motorcycle sprocket featuring a 48-tooth count and 520 pitch, finished in a striking red anodized coating. Engineered for performance-minded riders, this sprocket is part of Vortex's trusted aluminum sprocket lineup and is 100% CNC machined in the USA to precise tolerances.

Key Features:

• 48 Teeth — ideal for tuning acceleration and low-end torque response
• 520 Pitch — compatible with 520-size chain applications
• Red Anodized Aluminum Construction — reduces rotating mass compared to OEM steel sprockets for improved acceleration and handling
• 100% CNC Manufactured in the USA — machined to precise tolerances for concentricity and quiet operation
• Vortex Patented Tooth Design — unique profile increases sprocket longevity and chain engagement
• Specially Formulated Alloy — per Vortex specifications for optimal strength-to-weight ratio

The 491ZR-48 is a direct bolt-on rear sprocket replacement or gearing upgrade for compatible 520-pitch motorcycle applications. Running a higher tooth count rear sprocket increases low-end torque and acceleration at the cost of some top-end speed, making this an excellent choice for street and track performance tuning.
