When every gram and every detail counts on track, the LighTech OIL101 oil filler cap delivers race-grade engineering to your Aprilia RS 660 — CNC-machined from solid Ergal 7075 aluminium for a precision fit, genuine weight saving over the OEM cover, and the three safety-wire holes demanded by scrutineers at circuit events.
Key Features
- Three safety-wire drilling holes allow the cap to be wire-locked in full compliance with track-day and race regulations — a detail absent from the standard fitment.
- CNC-machined from solid Ergal 7075 aluminium billet: lighter and more resistant to heat than cast alternatives, with zero flex under repeated removal.
- Direct M20x1.5 thread match to the Aprilia RS 660 engine casing — plug-and-play replacement with no modification required.
- Laser-engraved LighTech logo adds a clean, understated finishing touch that holds its definition wash after wash.
- Anodised finish resists corrosion and oil staining, keeping the engine bay looking sharp between service intervals.
- 100% Made in Italy by LighTech, a specialist in precision CNC accessories trusted by teams from road to race.
Built for the Track, Refined for the Road
The OIL101 is not merely a cosmetic upgrade. Ergal 7075 is the same alloy grade used in aerospace and motorsport structural components — its high tensile strength means the cap threads in and out cleanly across the full temperature range of the RS 660 engine without risk of galling. The anodised surface treatment seals the aluminium at a microscopic level, so oil residue and heat cycles that would discolour a bare-metal part leave this cap unmarked.
For circuit use, the three evenly spaced safety-wire holes are the feature that truly separates the OIL101 from generic billet caps. Many track venues mandate safety-wiring of oil filler caps, and LighTech has pre-drilled the OIL101 to the correct geometry so your wire installer can work quickly and cleanly without drilling on-site.
