Kawasaki Ninja 400 EX400 Fairings
About the Kawasaki Ninja 400
The Kawasaki Ninja 400 (EX400) is a 399cc parallel-twin sport bike launched for 2018, replacing the Ninja 300 as Kawasaki’s lightweight supersport. It pairs a strong, usable powerband with a low seat height and light weight, making it a favourite for new riders, the A2 class in Europe, and talent-cup race series where it has become the default machine. Its sharp styling mimics the larger Ninja ZX-6R and ZX-10R, so it looks like a proper superbike despite the modest engine. Many owners refresh the fairings after a drop or build a track-day bike around the Ninja 400’s growing race support.
What sets the 400 apart from the 300 it replaced is the extra midrange and a more composed chassis, which is why it took over junior racing so quickly. It is not intimidating, but it is quick enough to be fun, and the riding position is roomy for a small sport bike. When the original plastic gets damaged, a fresh fairing set is the practical fix, and because so many 400s are ridden hard, the used market is full of bikes that benefit from a clean body.
Ninja 400 Generations & Year Ranges
The Ninja 400 arrived for 2018 and ran through 2023 with one core body shape, so fairings are consistent across that whole range. A related Ninja 400 ABS and later 440 share the same bodywork in most markets, with only trim and graphics differing. Confirm your bike is an EX400 (399cc), then browse the matching category for kits cut to that body. There is no year-split to worry about, which keeps ordering simple.
The only confusion is with the older Ninja 300, which looks similar but uses different panels. Check the engine size or the VIN if you are unsure, and compare your upper cowl with the product photos. Ordering the 300 kit for a 400 (or vice versa) is the most common mistake, and it is easy to avoid with a quick check before purchase.
Popular Ninja 400 Styles & Liveries
The showroom standard is Kawasaki Lime Green with black, the livery that defines the Ninja line and the easiest to resell. The KRT Edition adds the race-team green, black, and white graphics, while Metallic Carbon Grey and Phantom Blue offer quieter options for owners who want less attention. Green-and-black is by far the most common on the road and the track.
What’s Included in the Kit
A full Ninja 400 kit includes the upper fairing, the left and right side fairings, the lower belly pan, the tail section, and the front fender, plus the inner panels around the radiator. Some sets add a windscreen and tank cover, and the panels are colour-matched across the set. The 400’s compact fairing differs from the larger Ninja models, so the kit is moulded specifically to the EX400 shape and mounting points.
Fitment: Make Sure You Pick the Right Year
Ninja 400 fairings are moulded for the 2018-2023 body and do not fit the older Ninja 300. Check the engine size (399cc) or the VIN to confirm before ordering. The kits use pre-drilled OEM points, and a dry test-fit before final tightening is the safest way to confirm alignment, especially around the headlight and the lower belly pan where gaps show most.
