A chain and sprocket kit replaces the whole final drive at once: front sprocket, rear sprocket and chain. That is how these parts are meant to be replaced, because they wear together, and a kit takes the guesswork out of matching pitch, tooth counts and chain length.

Converts the Yamaha YZF-R6 (2003–2005) to 520 chain and quicker gearing, 15 / 50 (stock 16 / 48)

  • Driven 15T front sprocket, steel, Style 1041
  • Driven 50T rear sprocket, Style 5008: steel
  • D.I.D 520VX3 X-ring chain, 120 links, cut to 118 links for these sprockets (stock is 116). It comes with one master link: choose clip or rivet
  • Front sprocket, rear sprocket and chain in one order
  • Model-specific: check the fitment list for your bike

Fits

Bike Years Kit gearing (front / rear)
Yamaha YZF-R6 2003–2005 15 / 50

Stock is 16 / 48. This kit is one tooth smaller at the front and two larger at the rear: about 11% shorter overall gearing, so the bike pulls harder in every gear and tops out lower. A speedometer that reads from the gearbox or front sprocket will read fast. One down, two up is a common starting point, not the right answer for every bike or rider: ask us if you want a different setup.

Unless the listing says otherwise, a kit is built for stock gearing. Check the fitment list and tooth counts before ordering.

From the shop

We highly recommend a rivet-type master link on any street bike. Fitting one takes a chain riveting tool, which you can buy from us in the shop or online, or we can install your chain and sprockets for you.
