Vortex 202ZR-51 Black 51-Tooth Aluminum Rear Sprocket

The Vortex 202ZR-51 is a 51-tooth aluminum rear sprocket finished in a durable black hardcoat anodizing, designed for riders who demand lightweight performance with enhanced corrosion resistance. As part of Vortex's trusted 202-series rear sprocket lineup, this sprocket is 100% CNC machined in the USA from a specially formulated aluminum alloy to exacting tolerances.

Key Features:

• 51-Tooth rear sprocket for modified gear ratio tuning
• Black hardcoat (ZR) finish — PTFE-bonded anodizing for maximum durability and corrosion resistance
• 100% CNC machined in the USA from specially formulated aluminum alloy per Vortex specifications
• Vortex patented unique tooth profile designed to increase sprocket longevity
• Lightening holes reduce rotating mass for improved throttle response
• Silver anodized version also available (MPN: 202-51)

The Vortex 202ZR-51 is an ideal upgrade for riders looking to increase low-end torque and acceleration by running a larger rear sprocket tooth count. The black hardcoat finish offers superior wear resistance compared to standard silver anodizing, making it a popular choice for both street and track applications.
