LighTech Front Brake Reservoir Cap Aprilia RS 660 2020-2026 FBC04 — CNC Ergal Aluminium

Machined from solid Ergal 7075 aluminium and finished to genuine racing standards, the LighTech FBC04 reservoir cap transforms one of the most overlooked components on your Aprilia RS 660 into a precision-crafted detail that is every bit as purposeful as it looks. Where the factory plastic cap simply does a job, this anodised aluminium replacement does it with the kind of material integrity you would expect from an Italian race-parts specialist.

Key Features

• CNC-machined from solid Ergal 7075 aluminium — significantly stiffer and more durable than the OEM plastic cap it replaces
• High-grade anodised finish in your choice of seven colours, resistant to brake fluid contact and everyday handling
• Laser-engraved LighTech logo for a clean, factory-quality appearance that does not peel or fade
• Exact plug-and-play fitment for the Aprilia RS 660 — no modifications or adapters required
• Suits both the brake master cylinder reservoir and the clutch master cylinder reservoir depending on which side you are fitting
• Made in Italy by LighTech, a marque synonymous with precision aluminium accessories for performance motorcycles

Build Quality and Materials

LighTech machines the FBC04 from Ergal 7075, an aerospace-grade aluminium alloy chosen for its outstanding strength-to-weight ratio. The billet is cut from solid stock rather than cast, which eliminates the porosity and dimensional inconsistency that casting can introduce. Every surface is then anodised in racing quality to lock in the colour and protect the alloy against the chemical aggression of brake and clutch fluid — a detail that matters when the cap sits directly above the reservoir.

The LighTech branding is applied by laser engraving rather than a label or pad print, so it remains sharp regardless of how many times the cap is removed for fluid checks. The result is a component that genuinely earns its place in the cockpit rather than simply decorating it.

Colour Options and Part Numbers

The FBC04 is available in seven anodised colours, each with its own suffix for precise ordering:

• Black — FBC04NER
• Red — FBC04ROS
• Gold — FBC04ORO
• Green — FBC04VER
• Blue — FBC04COB
• Orange — FBC04ARA
• Silver — FBC04SIL

Fitment and Compatibility

The LighTech FBC04 is engineered specifically for the Aprilia RS 660 across all model years 2020 to 2026. It fits directly onto the OEM master cylinder reservoir — no drilling, no adaptation, and no specialist tools required. The cap can be fitted to either the front brake master cylinder reservoir or the clutch master cylinder reservoir depending on the side of the handlebar you are upgrading.
