Chain & Sprockets
- Vortex's V3 2.0 chains use X-ring seals, which Vortex state reduce friction compared with conventional seals.
Drilled side plates
- The chain's links are drilled, which Vortex state reduces rotating mass.
Tensile strength
- Vortex rate the 520 SX3 at 8,500 lb (37.8 kN), and for street use on bikes up to 750cc.
Steel front sprocket
- Vortex machine their fronts from steel for concentricity and durability, with lightening holes to take out rotating mass.
Laser-cut steel rear
- The rear is laser cut from steel.

Gearing — Staying Stock or Making a Change
On a 2019-or-later ZX-6R this kit matches the stock 15-tooth front and 43-tooth rear, so installing it keeps your bike at factory stock gearing. On a 2007–2018 ZX-6R, the stock front is 16 teeth, so this kit is one tooth down at the front.
Here is the general framework. Going one tooth smaller on the front shortens gearing — quicker acceleration, higher RPM at highway speeds, reduced top speed. The effect is roughly equivalent to adding two to three teeth to the rear sprocket. Going one tooth larger lengthens gearing — lower cruise RPM, softer pull from a stop. Stock gearing on these bikes is well matched for general street use. Neither direction is right or wrong — it depends on how and where you ride.
One practical note: the chain in this kit is cut to 112 links. A further change of more than a tooth or two can change the length you need, so work that out before you order, or ask us and we will work it out with you.

Description:Vortex 520 SX3 Gold Chain and Steel Sprocket Kit – Kawasaki ZX-6R ’07–26
Product Overview
A complete drive kit for the ZX-6R from 2007 on: a Vortex 520 SX3 X-ring chain in gold, a 15-tooth steel front sprocket and a 43-tooth steel rear. The chain is cut to 112 links.
What this kit does to your gearing depends on the year of your bike. On a 2019-or-later ZX-6R, 15/43 is the factory gearing, so this is a straight stock replacement. On a 2007–2018 ZX-6R, the factory front is 16 teeth, so this kit fits one tooth smaller at the front — quicker acceleration and higher revs at a given road speed than stock. It bolts on and the 112-link chain suits both, but it is a gearing change on the older bikes, not a like-for-like replacement.
Both sprockets are steel. Steel is heavier than aluminium but wears far more slowly, which is the practical choice on a bike that covers street miles. Vortex also make the same kit with a black chain, part number CK4103.
The master link is a rivet type, pressed closed with a chain tool rather than clipped on — if you are not set up to rivet one, have it done. ABS and non-ABS bikes take the same kit.
