Well I am not a fan of Choppers They seem to miss most the essential joy of a motorcycle-Cornering, working with the forces of nature while not exceeding the 1G we evolved with. (Rather than fighting them in a 4 wheeled machine while exceeding it)
With chopper you have supposed comfort and ease in a straight line but little else.
Having said that this is one of the better ones, the bars are not in a daft position and the suspension looks well thought out, and compared to the silly attempts at a motorcycle seen on the box (Orange county choppers et al) this is a far superior contraption as befits its supposed roots.
I am told that no Vincent components were lost in the construction of this art work and all were 'recycled' by Vincent owners, however its a pity the builder (sculptor?) did not just buy a new set of cases and start from there, because according to any known legal laws about specials, he has hardly gained enough components from the original machine to gain the title '1952' or 'Shadow' though it is undoubtedly black (I suspect Mr Thompsons song had a lot to do with the use of that name) Talk about a grave diggers spade*
