A small upgrade that makes a genuine difference every time you roll the bike out — the LighTech FFC03 rear brake fluid reservoir cap replaces the stock plastic cover on the Aprilia RS 660 with a precisely CNC-machined piece of Ergal 7075 aluminium, giving you a durable, corrosion-resistant finish and a cleaner look without any fuss.
Key Features
- Direct OEM fit for the rear foot-brake reservoir on the Aprilia RS 660 (2020–2026) — plug-and-play installation, no modification required
- CNC-machined from solid Ergal 7075 aluminium, the same high-strength alloy used in competition components
- Colour-anodised finish in five options — black, red, gold, silver or blue — so you can match your bike's livery exactly
- Laser-engraved LighTech logo for a factory-quality finish that won't fade or peel
- Genuine LighTech part, designed and manufactured in Italy
Everyday Value in a Simple Swap
Not every upgrade needs to be radical to be worthwhile. The stock reservoir cap on the RS 660 is purely functional — adequate, but unremarkable. The LighTech FFC03 keeps every bit of that practicality intact while adding a considered, purposeful detail that enthusiasts notice. Because it fits directly onto the original reservoir, there is nothing complex about the installation: remove the old cap, fit the new one, and the job is done. The anodised finish handles daily exposure to brake fluid, heat and road grime without complaint, making this a genuinely low-maintenance improvement rather than a cosmetic indulgence you have to baby.
Build Quality
Ergal 7075 is a premium aerospace-grade aluminium alloy chosen for its exceptional strength-to-weight ratio and resistance to corrosion — significantly tougher than the standard 6061 alloy used in many aftermarket accessories. Machining it from solid billet rather than casting it ensures precise thread engagement, a reliable seal and a surface finish that takes the anodising evenly across the entire piece. The laser-engraved LighTech branding is recessed into the material, meaning it remains crisp and legible regardless of how many kilometres you accumulate.
Fitment & Compatibility
This cap is designed specifically for the small-format rear brake fluid reservoir fitted to the Aprilia RS 660. Confirmed fitment covers all model years from 2020 through to 2026. It is not intended for the front master cylinder reservoir.
