Product Details

The Vortex 165ZK-50 is a 50-tooth, 420-pitch aluminum rear sprocket finished in a black anodized coating. Precision-engineered by Vortex Racing in the USA, this sprocket is designed as a direct performance upgrade over heavy stock steel units, reducing rotating mass for sharper throttle response and improved acceleration.

Key Features:

  • Chain Pitch: 420
  • Tooth Count: 50 teeth
  • Material: Specially formulated aluminum alloy per Vortex specifications
  • Finish: Black anodized for corrosion resistance and a clean race-ready appearance
  • Manufacturing: 100% CNC machined in the USA to precise tolerances ensuring concentricity
  • Design: Unique tooth profile engineered to extend sprocket and chain lifespan
  • Weight Savings: Significantly lighter than OEM steel sprockets, reducing rotating mass for improved performance

Vortex Racing rear sprockets are trusted by racers and street riders alike for their superior quality, consistent fitment, and long service life. The 165ZK-50 is an ideal upgrade for riders looking to fine-tune gear ratios or replace a worn OEM sprocket with a high-performance alternative.

5 Star

Had received two deck chairs as a gift and were impressed with their quality and comfort. Decided to order 3 more. Can't have enough when gathering with friends and family.

Easy ordering process

The product was in stock as advertised and received promptly; as compared to other that advertise but do have the item available at all.

Items arrived quickly - don't remember receiving any shipping notification though beforehand

So far so good!!!
