Vortex 491-56 56-Tooth Rear Sprocket

The Vortex 491-56 is a high-performance 56-tooth rear sprocket engineered for riders seeking improved acceleration and drivetrain response. Manufactured by Vortex Racing, a trusted name in motorcycle sprockets and drivetrain components, this sprocket is precision-machined from high-grade aluminum alloy for an optimal balance of strength and weight savings.

Key Features:

• 56 teeth for increased low-end torque and improved acceleration
• Precision CNC-machined from high-strength aluminum alloy
• Hard anodized finish for corrosion resistance and long service life
• Lightweight construction reduces unsprung rotational mass
• Compatible with standard OEM chain pitch for easy installation
• Manufactured to tight tolerances for smooth, quiet chain engagement

Vortex sprockets are a popular upgrade for sport bike and street riders looking to fine-tune their gearing ratio. A higher tooth count rear sprocket like the 491-56 shortens overall gearing, delivering stronger acceleration out of corners and from stops. This sprocket is a direct OEM-style replacement that installs using factory hardware.
