GSXS Rizoma Brake Reservoir
I added Brembo RCS Master Cylinder to a Suzuki GSXS so needed to add new fluid reservoirs so added a GSXS Rizoma Brake reservoir with a rear to match. The Rizoma reservoirs are blue anodized alloy with a clear window on the front brake reservoir.
CT125U and CT451B at front
CT115U and CT450B rear
Its much easier to see the fluid level in the front reservoir than the original non-radial master cylinder with built in reservoir.
