Product Details

The Vortex CK2256 is a complete GFRA (GoFast) 520 conversion chain and sprocket kit engineered for riders seeking improved acceleration through optimized gearing. This ready-to-install kit requires no chain cutting and includes a front sprocket, hardcoat aluminum rear sprocket, and a Japan-made 520RV3 chain — everything needed for a direct bolt-on installation.

Gearing Specifications:

  • OE (Factory) Gearing: 16T front / 40T rear
  • Vortex Kit Gearing: 15T front / 40T rear (one tooth down in front, stock rear)
  • Chain Type & Length: 520RV3 — 104 links

Chain Features:

  • Japan-manufactured to the highest quality specifications in the industry
  • SV3 Series dual pocket sealing system delivers up to 7× longer wear life vs. standard O-ring chains
  • Includes rivet-type master link for a secure, race-proven connection

Sprocket Features:

  • Rear sprocket: F5 PTFE Black Hardcoat aluminum — hard anodized with a PTFE coating for added lubricity and corrosion resistance
  • Front sprocket: High carbon steel with induction hardening and drilled lightening holes to reduce rotating mass
  • Precise tolerances ensure concentricity and smooth power transfer

By dropping one tooth on the front sprocket, this kit lowers the overall gear ratio for quicker acceleration off the line without changing the rear sprocket size. Compare OE gearing to Vortex kit gearing to verify the ratio difference before installing.

Great price!

I like the free shipping for this order.

So far, I really enjoyed the speedy checkout and great prices.

Great price and fast shipping! Tech support helped me before the sale to make sure I was ordering the right part

So far so good

Very easy so far.

I hope this time there will be no problem or cancellation of my order from your end, as I confirmed the stock from your sale department personnel (Hector) before I proceed on checking out.
