When track regulations demand wire-locking and only precision-grade components will do, the LighTech OIL111 oil filler cap for the Kawasaki ZX-4 RR (2023–2025) delivers exactly that. CNC-machined from Ergal aluminium and finished to an exacting standard, it replaces your stock cap with a part engineered for riders who take both performance and safety seriously.
Key Features
- Three integrated drilling holes allow wire-locking in full compliance with trackday and circuit regulations — a mandatory safety requirement at most race venues.
- CNC-machined from Ergal aluminium for an exceptional strength-to-weight ratio, combining structural rigidity with minimal mass addition.
- Ultralight, temperature-resistant and vibration-proof construction stands up to the thermal and mechanical demands of hard track use.
- Laser-engraved LighTech logo confirms genuine manufacture quality and adds a clean, purposeful aesthetic.
- Direct plug-and-play fitment — remove the original cap, thread in the LighTech unit, and you are done. No modifications required.
- Available in six anodised colours to complement your ZX-4 RR livery: black, red, silver, gold, blue, and green.
Built for the Track, Refined for the Road
The thread specification of M20 x 2.5 matches the Kawasaki ZX-4 RR's oil filler aperture precisely, ensuring a secure, leak-free seal under all operating conditions. Ergal aluminium — the high-strength 7075 alloy long favoured in motorsport — resists heat soak and cyclical stress in a way that standard alloys simply cannot. Whether you are heading to a sprint day, a club race or simply want trackday-legal hardware fitted year-round, this cap fulfils the requirement without compromise.
The wire-locking holes are the defining safety detail here. Scrutineers at closed-circuit events require oil filler caps to be wire-locked so that vibration cannot cause accidental loosening and an oil spill on track. The LighTech OIL111 is designed with this regulation built in from the outset — not as an afterthought.
Fitment and Compatibility
This cap is engineered specifically for the Kawasaki ZX-4 RR across the 2023, 2024 and 2025 model years. Thread size M20 x 2.5. Verify your engine oil filler thread specification before ordering if you have had any non-standard engine work carried out.
