Here are a few pictures of my friend Sid's Street Triple - Rob North special All parts were fabricated and welded by him.
Is the Tank a cover for a container or a tank? Did he cut or remove the rear sub-frame. Very clean job, it seems like these wishbone frames are not the easiest to customise well. Your friend managed it.
It was a little while ago, so I can't remember what was done regarding the sub frame, but the tank is the real thing in aluminium, with the under side being an amazing complex of shapes to fit the form of the parts underneath.
I like that a lot, have been wondering for a few months what could be done with the rear of a Street....Food for thought
