Chain & Sprockets
- 2018–2023 Kawasaki Ninja 400
Product Overview
This kit fits the 2018–2023 Kawasaki Ninja 400. The 14-tooth front sprocket matches stock. The 44-tooth rear sprocket is three teeth over the stock 41-tooth rear — this is a gearing change, not a stock replacement. Installing this kit shortens your gearing compared to factory: quicker pull from a stop, higher RPM at highway speeds, reduced top-end.
The 520 chain matches the Ninja 400's stock chain pitch, so no conversion is required. Everything in this kit installs directly without changing chain size.
Key Technology & Design
The front sprocket is induction hardened steel, lightened with radial holes. The rear sprocket is laser-cut steel with an electro-plated satin black finish. The SX3 chain uses a tri-glide X-ring seal design that creates three pockets of lubrication per link. Compared to standard O-ring chains, this reduces heat and friction and extends wear life. The chain includes a rivet-type master link.

Gearing — Staying Stock or Making a Change
This kit installs a 14-tooth front — stock size for the Ninja 400 — and a 44-tooth rear, which is three teeth over the stock 41-tooth rear.
The net effect of the rear change: shorter gearing. Acceleration from a stop is quicker, RPM at highway cruise is higher, and top-end speed is reduced. If you want to stay at factory gearing, a 41-tooth rear is what you're looking for.
If you are considering additional gearing changes, 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 on the front lengthens gearing — lower cruise RPM, softer pull from a stop.
Stock gearing on the Ninja 400 is well matched for general street use. The direction you go depends on how and where you ride.
