The Vortex 775AZRV4-50 is a 50-tooth, 525-pitch aluminum rear sprocket engineered for performance motorcycle applications. Machined from aircraft-grade aluminum and finished with a clear anodize, this sprocket delivers a significant weight reduction over OEM steel units — reducing rotating mass for improved throttle response and acceleration.

Key Features:

• 50-Tooth, 525 Pitch — direct-replacement sizing for compatible 525-chain drive systems
• 7075-T6 Aluminum Construction — high-strength alloy for outstanding durability-to-weight ratio
• 100% CNC Machined — manufactured in the USA to tight tolerances for precise chain engagement and long service life
• Clear Anodized Finish — corrosion-resistant coating that protects against the elements and road grime
• Patented Tooth Profile — Vortex's unique tooth geometry promotes even chain wear and extends sprocket longevity
• Gunk-Clearing Tooth Grooves — debris-relief cuts between teeth help keep the drive clean under race and street conditions

The Vortex 775AZRV4-50 is a proven choice for both track riders and performance street enthusiasts who demand the weight savings and precision of an aluminum sprocket without sacrificing durability. Designed as a bolt-on replacement for compatible applications using the RV4 bolt pattern.
