This is an original BREMBO manifold for rear brake lines which sits on the frame for SD900 & SS900 Darmahs.
It has been cleaned, blasted and newly refinished with black ceracote.
The brake line goes from the master cylinder to this, another brake line goes to the caliper and sometimes there is a brake light switch in 1 of the holes as well. This is the exact item as found on all Bevel Drive Ducati Darmahs on the back brake.
