Product Overview
POSH Φ38mm OD / 32.5mm ID MASTER CYLINDER CAP, "ANODISED BLACK", 500154-06
If you are looking to replace or upgrade your "clutch / brake" master cylinder cap on your next custom build or "retro-inspired" project, you can do so with our POSH "Black Anodised" CNC machined alloy master cylinder caps (with Φ32.5mm ID, & 38mm OD). The black anodising looks a treat contrasting against polished parts or with stealth black parts.
The 32.5mm (ID) version here suits the "Nissin clutch master cylinders", some "rear Nissin brake master cylinders", Galespeed "GS15 and GS15SR" master cylinders and our small Nissin "smoked fluid tank". This allows you to match master cylinder caps when customising!
These unique, CNC-machined aluminium master cylinder caps are a classic long time selling part in Japan. And they are proudly crafted in Japan by POSH FAITH so they exceed the quality of similar products on the market. The precision-machined surface ensures a superior finish as shown. The included 2025 updated silver-on-black POSH ("Efficient Sports") badge can be used or omitted depending on your preference. The cap itself has no additional markings, making it ideal for custom builds, general use, or even laser etching with your own design.
Perfect for high-end custom builds or general use, these black anodized caps add a touch of distinction compared to the old plastic caps. Weather your looking to stand out, or blend into that custom bike build, check out the full range of POSH black anodised parts now available in the VANEM store!!
Made in Japan ensuring excellent craftsmanship and quality.
