Product Details

The Vortex 527ZK-40 is a Cat5 series rear sprocket machined from lightweight, high-strength aluminum and finished in a durable black anodized coating. Designed as a direct OEM-replacement-style upgrade, this 40-tooth sprocket is a popular choice for riders looking to reduce unsprung rotational mass without sacrificing durability or precision.

Vortex sprockets are manufactured using CNC-machined 7075-T6 aluminum, providing an excellent strength-to-weight ratio over stock steel sprockets. The black hard anodized finish resists corrosion and wear, extending the service life of the sprocket under demanding track and street riding conditions.

Key Features:

  • Series: Cat5 rear sprocket
  • Tooth Count: 40 teeth
  • Chain Pitch: 527
  • Material: CNC-machined aluminum
  • Finish: Black hard anodized
  • Construction: Precision CNC machined for accurate tooth profile and consistent chain engagement
  • Lightweight aluminum construction reduces unsprung rotational weight compared to OEM steel sprockets
  • Direct bolt-on replacement for compatible applications

The Vortex Cat5 rear sprocket line is a trusted choice among sport bike enthusiasts and racers seeking reliable performance upgrades. Compatible with 527-pitch drive chains, this sprocket delivers precise power transfer and smooth chain engagement lap after lap.

Not enough product's information to identify the correct item to purchase.

Very Good

I did a price comparison for hard-to-find Redline motor and tranmission oil of over 30 different vendors and websites through Amazon, E-bay, Google, etc. and Autoplicity had the best price by 25-30%. It was a no-brainer to order from them, and their website is easy search and manage. And their shipping charges aren't too bad either.
