Upgrading the rear brake reservoir cap on your Kawasaki Ninja 400 (2018–2023) is one of the simplest, most cost-effective ways to sharpen the bike's appearance and add a lasting quality touch. The LighTech FFC05 slots straight in with no modifications, giving you aerospace-grade ERGAL aluminium construction and a laser-engraved finish that will outlast the original plastic cap by a considerable margin.
Key Features
- CNC-machined from solid ERGAL aluminium — a lightweight, high-strength alloy used in aerospace applications — for exceptional rigidity and resistance to heat and brake fluid
- Anodised surface finish resists corrosion, UV fading and the chemical aggression of DOT brake fluid over years of daily use
- Direct, tool-friendly fitment — precision-machined to OEM tolerances so it installs in minutes with no drilling, cutting or adapter required
- Laser-engraved LighTech logo guarantees 100% authentic product identification
- Available in five colours — Black, Gold, Red, Cobalt Blue and Green — so you can match or contrast your Ninja 400's livery
- Equally at home on the road or track, adding a purposeful, finished look to the rear brake circuit
Everyday Value, Race-Quality Build
Not every upgrade needs to be complicated or expensive. The LighTech FFC05 proves that a small detail can make a big difference: the moment you swap the factory resin cap for this machined ERGAL unit, the rear brake reservoir area looks like it belongs on a prepared race machine rather than a showroom bike. Because the cap is cut to exact OEM dimensions, fitment takes only a few minutes — no fuss, no guesswork. Whether you commute on your Ninja 400 or take it to track days, the anodised finish holds its colour and sheen under heat cycles and wet conditions that would leave painted or plastic parts looking tired.
Material and Durability
ERGAL aluminium is chosen by LighTech for the same reasons aerospace engineers favour it: an outstanding strength-to-weight ratio, natural resistance to fatigue, and excellent stability at elevated temperatures. The anodised outer layer seals the surface at the microscopic level, creating a barrier that brake fluid, rain and road grime cannot penetrate. The result is a reservoir cap that will still look as good after several seasons of hard use as the day it was fitted.
