Product Details

The Vortex 151ZR-39 is a 39-tooth, 420-pitch CAT5 aluminum rear sprocket finished in a distinctive red anodize. Engineered for small-displacement motorcycles and mini-bikes running 420-chain drive systems, this sprocket delivers a reliable, lightweight upgrade over OEM steel units.

Key Features:

  • Chain Pitch: 420
  • Tooth Count: 39 teeth
  • Material: Lightweight aluminum construction
  • Finish: Red anodized for corrosion resistance and visual appeal
  • Design: Vortex patented CAT5 M-tooth profile for extended sprocket and chain life
  • Position: Rear sprocket

Vortex's CAT5 tooth geometry is engineered to reduce chain wear and improve power transfer efficiency. The aluminum construction keeps unsprung weight low, while the red anodized finish provides a durable, corrosion-resistant surface. A direct bolt-on replacement or performance upgrade for compatible 420-chain applications.
