Motorcycle Brake Fluid Reservoir Cup Universal CNC Aluminum Green

Universal Motorcycle Brake Fluid Reservoir Cup in Green CNC Aluminum

This motorcycle brake fluid reservoir cup replaces a cracked, faded or leaking stock reservoir on your brake or clutch master cylinder. The cup is CNC machined from billet aluminum with a clear PMMA sight window, so you can check your fluid level at a glance and give your handlebar setup a clean custom look at the same time. The anodized green finish resists fading and stands up to sun, rain and road grime.

Fits Honda, Yamaha, Kawasaki and Suzuki

The universal design fits most metric bikes, including popular Honda, Yamaha, Kawasaki and Suzuki sport bikes, cruisers and naked bikes. Choose the version with the mounting bracket for a complete bolt on kit, or the cup only if your existing bracket is still in good shape. Installation takes minutes with basic hand tools.

Frequently Asked Questions

Will this brake fluid reservoir fit my motorcycle?

It uses a universal design that fits most metric motorcycles from Honda, Yamaha, Kawasaki and Suzuki. If your bike uses a standard handlebar mounted master cylinder reservoir, this cup will work.

Can I use it for the clutch as well as the brake?

Yes. It works as a front brake fluid reservoir or a hydraulic clutch fluid reservoir, as long as your clutch is hydraulic.

What is the difference between the two options?

One option includes a mounting bracket that clamps to your handlebar, the other is the reservoir cup only. Pick the bracket version if you are replacing the whole assembly.

Is it compatible with DOT brake fluid?

Yes. The aluminum body and sealed gasket are made for standard DOT 3 and DOT 4 brake fluid used in motorcycle brake and clutch systems.

Is it hard to install?

No. Most riders swap it in minutes with basic hand tools. Top up with fresh fluid after fitting and check for leaks before riding.

Will the green finish fade in the sun?

The anodized finish is made to resist UV fading and weather, so it keeps its color through daily riding.
