Product Details

The Vortex 630ZK-51 is a precision-machined rear sprocket designed for motorcycles running a 630 pitch chain. Featuring a 51-tooth configuration, this sprocket delivers a lower final drive ratio for increased low-end torque and acceleration — ideal for riders who want stronger pull out of corners or who frequently ride in demanding, stop-and-go conditions.

Vortex sprockets are manufactured to exacting tolerances using high-quality steel, ensuring long service life and consistent chain engagement. Each sprocket is heat-treated for superior wear resistance, helping the drivetrain maintain optimal performance mile after mile.

Key Features:

  • 51-tooth rear sprocket for lower gearing and increased torque
  • 630 chain pitch compatibility
  • High-strength steel construction with heat treatment for durability
  • Precision CNC machined for accurate tooth geometry and smooth chain engagement
  • Direct OEM-style replacement fit
  • Part of Vortex's trusted ZK sprocket lineup

Whether you are replacing a worn OEM sprocket or re-gearing your motorcycle for a specific riding style, the Vortex 630ZK-51 is a reliable, high-quality upgrade that delivers consistent drivetrain performance.

I ordered the wrong part

It was great extremely fast shipping

Every thing went fast with no problems while ordering

Excellent 1st time buying experience.

The only complaint I have is, your product does not list the OZ. of the products. You need to add alittle more detail.

Didn't get to use it got too cold, Ready to go ice fishing have to try it in the summer.

Quick service. Only concern was that your check out/payment process seemed clunky. My order went through but I also received emails saying it had failed. I called customer service and they confirmed that the order did process.

Easy finding part and good pricing

Quick and easy
