Product Details

The Vortex 313ZR-42 is a 42-tooth CAT5 aluminum rear sprocket engineered for sport motorcycle applications. Part of Vortex Racing's industry-leading sprocket lineup, this rear sprocket delivers a precision-fit, lightweight alternative to OEM steel sprockets, reducing unsprung and rotational mass for improved throttle response and acceleration.

Key Features:

  • 42-tooth rear sprocket for optimized gear ratio tuning
  • Lightweight CAT5 aluminum construction — significantly lighter than steel alternatives
  • 100% CNC machined in the U.S.A. to precise tolerances
  • Specially formulated alloy per Vortex Racing specifications
  • Anodized finish for corrosion resistance and lasting appearance
  • Patented tooth profile designed to extend sprocket and chain life
  • Direct bolt-on replacement — no modifications required

Vortex Racing sprockets are trusted by professional racers and performance street riders alike. The 313ZR-42 is an ideal upgrade for riders looking to fine-tune their gear ratio or replace a worn rear sprocket with a high-quality, race-proven component.

I would think these would be sold in pairs

VERY EASY TO ORDER AND CHECK OUT.

The purchasing process was easy...no problem. Waiting to see how the rest of it goes before I rate further (shipping, product condition, etc.)

The site is easy to use. Prices are very reasonable. We had an issue with the shipment customer service was able to provide an agreeable solution for us. Thank you!!
