Honda Ruckus Billet Coolant Reservoir Cap

Billet Coolant Reservoir Cap for Honda Ruckus and Metropolitan Scooters

This machined aluminum coolant cap is meant to take the place of the stock plastic cap on Honda's liquid-cooled scooters. It sits flush on Honda Ruckus models and gives the engine bay a tidy, personalized look. It is one of the Honda Ruckus scooter parts that updates how your ride looks while still keeping the coolant reservoir sealed.

Precision Engineering

Cut from a single solid block of aluminum, this cap is CNC-machined to achieve a close fit and a clean surface. Unlike the factory plastic piece, it is not prone to cracking or fading with age. The polished black anodized coating looks sharp and also helps resist everyday wear.

Custom Design Features

A laser-etched tribal pattern on the cap gives your scooter a distinctive detail. The tall fin design makes it easy to remove and retighten, including when you are wearing gloves or the engine is still hot. This upgrade suits Ruckus frames that have been altered to show the coolant reservoir.
