Vortex 920ZB-46 Aluminum Rear Sprocket Chain Pitch Sprockets - 46-Tooth 520

The Vortex 920ZB-46 is a high-performance 46-tooth aluminum rear sprocket designed for motorcycle applications requiring lightweight drivetrain components. Machined from aircraft-grade aluminum, this sprocket delivers an excellent strength-to-weight ratio over stock steel sprockets, helping reduce unsprung and rotating mass for improved throttle response and acceleration.

Key Features:

• 46-Tooth count for optimized gear ratio and drive performance
• 520 chain pitch compatibility for a wide range of sport and street bikes
• CNC-machined from high-strength aluminum billet for precision fitment and consistent performance
• Hard-anodized finish for corrosion resistance and extended service life
• Lightweight construction reduces rotating mass compared to OEM steel sprockets
• Direct bolt-on replacement — no modifications required
• Manufactured by Vortex Racing, a trusted name in motorsport drivetrain components

The Vortex 920ZB-46 is an ideal upgrade for riders looking to fine-tune their final drive ratio or reduce overall drivetrain weight. As with all Vortex sprockets, precise CNC machining ensures consistent tooth profiles for smooth, quiet chain engagement and reduced wear on both the sprocket and chain.
