Vortex 823C-51 Rear Sprocket Steel Motorcycle Chain Drive Sprockets - 51T

The Vortex 823C-51 is a 51-tooth steel rear sprocket designed as a direct OEM-replacement or performance upgrade for compatible motorcycles. Vortex is a trusted name in motorcycle drivetrain components, manufacturing sprockets to tight tolerances for reliable chain engagement, reduced wear, and consistent power transfer from the engine to the rear wheel.

Key Features:

• 51 Teeth — increases rear drive ratio for improved low-end torque and acceleration response
• Steel construction — provides excellent durability and longevity under demanding riding conditions
• Precision CNC machined — ensures accurate tooth profile and consistent chain engagement
• Direct bolt-on fitment — engineered to match OEM mounting specifications for the 823C carrier series
• Heat-treated finish — resists corrosion and extends service life

Replacing your rear sprocket with a higher tooth count like the 823C-51 lowers your final drive ratio, delivering stronger acceleration and improved low-speed torque — ideal for street riding, commuting, or track applications where quick throttle response is prioritized. Always replace the chain and front sprocket together for maximum drivetrain longevity.
