Vortex 254ZR-48 VTX Aluminum Rear Sprocket 48-Tooth

The Vortex 254ZR-48 is a 48-tooth aluminum rear sprocket engineered for motorcycle riders who demand lightweight performance without sacrificing durability. Machined from 7075 T6 aerospace-grade aluminum, this sprocket delivers a significant weight reduction over stock steel units, directly reducing rotating mass for improved throttle response and quicker acceleration.

Key Features:

• 48-Tooth Rear Sprocket — allows for precise gearing adjustments to suit street or track riding styles
• 7075 T6 Aerospace Aluminum Construction — high-strength alloy provides an ideal balance of lightness and durability
• 100% CNC Machined — manufactured to tight tolerances for a perfectly concentric sprocket and consistent chain engagement
• Optimized Tooth Profile — reduces chain friction and drag for smoother power delivery during both acceleration and deceleration
• Clear Anodized Finish — protective coating helps resist oxidation and corrosion while maintaining a clean silver appearance
• Patented Vortex CAT5 Design — iconic two-tone machined look with mud-clearing grooves between teeth to keep the drivetrain clean
• USA Manufactured — produced domestically by Vortex Racing to strict quality standards

Upgrading to the Vortex 254ZR-48 aluminum rear sprocket is one of the most effective ways to reduce unsprung and rotating weight on your motorcycle. Vortex recommends cleaning the chain and sprocket every 300–400 miles to maximize service life when running aluminum sprockets. Compatible with the matching chain pitch — always ensure your front sprocket and chain are the same pitch as this rear sprocket for proper drivetrain function.
