The LighTech TRN223 is a precision-engineered CNC fuel cap designed specifically for the Kawasaki Ninja 400 from 2018 to 2023. Manufactured entirely in Italy to genuine motorsport standards, it replaces the standard screw cap with a tool-free push-and-pull quick-release mechanism — shaving refuelling time at the track and adding a distinctly race-bred aesthetic to your Ninja.
Key Features
- Push and pull quick-release mechanism — open the tank in seconds without any tools, ideal for rapid pit stops or everyday convenience
- Machined from solid billet aluminium in a single CNC operation for exceptional strength and a consistent, close-tolerance fit
- Anodised finish on both exterior and interior surfaces — colour-stable, corrosion-resistant and built to outlast the bike's service life
- Exterior finished in black anodised aluminium; interior colour varies by variant (red, black or green) for a subtle two-tone, motorsport-inspired detail
- Supplied complete with fitting bolts and a seal — everything required for a direct, no-modification installation
- 100% Made in Italy — the same manufacturing philosophy behind LighTech's full track-day and race-homologated accessory range
Precision Manufacturing and Build Quality
LighTech mills the TRN223 from a single piece of solid aluminium billet using multi-axis CNC machining. This one-piece construction eliminates the weak points inherent in cast or multi-part designs, delivering a cap that is simultaneously lighter than the OEM unit and structurally superior. The anodised surface treatment penetrates the aluminium rather than sitting on top of it, meaning the colour and corrosion resistance are intrinsic to the material — not a coating that chips or flakes under fuel exposure or UV light.
The Push and Pull Opening System
The push-and-pull mechanism replaces the conventional threaded cap with a system borrowed directly from competition motorcycles. Press the cap inward to disengage the locking tabs, rotate, and lift — the entire sequence takes a fraction of the time required by a standard screw cap. The seal included in the delivery ensures a fuel-tight closure that meets the demands of both road and circuit use, with no compromise on safety despite the speed of operation.
Fitment and Compatibility
The LighTech TRN223 is a direct, vehicle-specific replacement designed to fit the following motorcycle:
- Kawasaki Ninja 400 — model years 2018, 2019, 2020, 2021, 2022 and 2023
No cutting, drilling or modification to the fuel tank or surrounding bodywork is required. The supplied fitting bolts ensure a secure, rattle-free installation using standard workshop tools.
