Vortex 200EZR-51 Easy-Change Rear Sprocket 51T

The Vortex 200EZR-51 is a high-performance 51-tooth Easy-Change rear sprocket engineered for sport and street motorcycle applications. Vortex's EZR (Easy-Change Rear) series is designed to bolt directly onto the OEM rear sprocket carrier, allowing quick sprocket swaps without the need to remove the rear wheel hub or carrier assembly.

Manufactured from 7075-T6 billet aluminum, this lightweight sprocket delivers exceptional strength-to-weight ratio while resisting corrosion and wear under demanding riding conditions. The precision CNC-machined tooth profile ensures smooth, quiet chain engagement and maximizes drivetrain efficiency.

Key Features:

• 51-tooth rear sprocket for increased low-end torque and acceleration
• EZR Easy-Change design — mounts to stock rear sprocket carrier for fast installation
• CNC-machined from 7075-T6 billet aluminum for a superior strength-to-weight ratio
• Hard anodized finish for corrosion resistance and long service life
• Precision tooth geometry for smooth, consistent chain engagement
• Direct OEM replacement bolt pattern — no modifications required

The Vortex 200EZR-51 is an ideal upgrade for riders seeking improved acceleration and throttle response over the stock gearing setup. As with all Vortex drivetrain components, it is designed to meet or exceed OEM tolerances for a precise, reliable fit.
