This is a very early aluminum round reservoir BREMBO cap with new rubber bellows.
I have blasted and refinished the cap with a chemical resistant finish commonly used in the firearms industry so it looks original and will last.
It is perfect condition. This cap will fit bevel drive twins front brembo round reservoir master cylinder that came on 750GT, 750 sport, 860 & 900 GT/S, Darmah, 900 Super Sport etc.
