The LighTech TRN223 replaces the stock fuel cap on the Kawasaki ZX-4 RR (2023–2025) with a precision-engineered, push-and-pull quick-release unit machined from CNC-milled aluminium in Italy — a genuine race-derived solution that meets the demands of both road and track use with complete confidence.
Key Features
- Push and pull quick-release mechanism opens and closes the tank instantly — no key, no tools, no fumbling at pit lane or fuel stops
- CNC-milled from high-grade aluminium, anodised for corrosion resistance and long service life
- Exterior finished in classic black anodising; interior colour-matched accent in red, black or green depending on chosen variant
- Direct OEM-replacement fitment for Kawasaki ZX-4 RR model years 2023, 2024 and 2025
- Includes mounting hardware and seal for a complete, hassle-free installation
- 100% Made in Italy — manufactured under LighTech's exacting motorsport quality standards
Race-Derived Engineering for the Road
LighTech has supplied components to professional paddocks for decades, and the TRN223 carries that heritage directly to the ZX-4 RR. The push-and-pull closure system is the same principle used in competition fuel caps: depress the centre, rotate, lift. What takes seconds on a race bike now takes seconds on yours. The aluminium construction reduces unsprung and reciprocating mass compared to the standard plastic and rubber cap assembly, while the anodised surface resists fuel spills, UV exposure and the general abuse of daily riding.
Finish and Aesthetics
The exterior of every TRN223 variant is finished in understated black anodising, keeping the look purposeful rather than garish. The coloured interior accent — visible when the cap is open — is the detail that distinguishes each variant: red brings an aggressive contrast against the ZX-4 RR's livery options, black keeps everything monochrome and stealth, and green is the natural nod to Kawasaki's iconic racing heritage. Whichever you choose, the cap reads immediately as an aftermarket upgrade without shouting about it.
Fitment and Compatibility
The LighTech TRN223 is designed and manufactured specifically for the Kawasaki ZX-4 RR across all production years currently available:
- Kawasaki ZX-4 RR — 2023
- Kawasaki ZX-4 RR — 2024
- Kawasaki ZX-4 RR — 2025
It is a direct replacement for the original fuel cap and requires no modification to the tank neck or filler surround.
