Vortex 775ZBV4-47 VTX Aluminum Rear Sprocket 47T

The Vortex 775ZBV4-47 is a 47-tooth VTX Series aluminum rear sprocket designed as a direct-fit, performance upgrade over the stock steel sprocket. Engineered by Vortex Racing — a trusted name in competitive and street motorcycle drivetrain components — this sprocket is precision-machined from high-strength 7075-T6 aluminum and hard-anodized for durability and corrosion resistance.

Key Features:

• 47-Tooth Count — alters final drive ratio for improved acceleration or top-speed tuning depending on front sprocket pairing
• 7075-T6 Aluminum Construction — significantly lighter than OEM steel sprockets, reducing unsprung and rotating mass
• Hard-Anodized Finish — provides a hard, wear-resistant surface and corrosion protection
• VTX Series Design — features Vortex's signature scalloped lightening cuts for maximum weight savings without sacrificing strength
• Precision CNC Machined — ensures accurate tooth geometry and consistent chain engagement for smooth, reliable power transfer
• Direct OEM Replacement Fit — mounts using the stock hub pattern for straightforward installation

The Vortex VTX aluminum rear sprocket is a popular choice for riders looking to reduce overall drivetrain weight and fine-tune gearing on the track or street. Compatible with the appropriate chain pitch for the application, this sprocket pairs seamlessly with Vortex front sprockets for a complete drivetrain solution.
