Vortex 435-48 Silver 48-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 435-48 is a high-performance aluminum rear sprocket offering a significant weight advantage over standard steel OEM sprockets. Constructed from a specially formulated 7075-T6 aluminum alloy and 100% CNC machined in the USA, this sprocket delivers the precision and durability demanded by serious riders. The silver finish is achieved through a clear anodizing process that provides corrosion resistance while giving the sprocket a bright, polished appearance.

Key Features:

• 48 Teeth, 520 Pitch — direct-fit rear sprocket for 520-chain applications
• 7075-T6 Aluminum Construction — specially formulated alloy per Vortex specifications for optimal strength-to-weight ratio
• 100% CNC Machined in the USA — tight tolerances ensure a perfectly concentric sprocket for smooth, efficient power transfer
• Vortex Patented Tooth Design — engineered to reduce drag and friction while extending sprocket and chain life
• Silver Anodized Finish — clear anodizing resists corrosion and maintains a clean, polished look
• Mud Grooves — designed to shed debris and keep the drivetrain running cleanly
• Reduced Rotating Mass — lighter drivetrain components improve throttle response and acceleration
• Available in single-tooth increments for precise gearing adjustments

By reducing rotating mass in the drivetrain, the Vortex 435-48 improves acceleration response compared to heavier stock sprockets. The patented tooth geometry minimizes chain wear for a longer service life across both the sprocket and chain. A trusted choice for sport, street, and track riders looking to optimize their motorcycle's drivetrain performance.
