Take a look at this Z1

The photos as always make it look way better than reality, but the paint is new, it's a genuine UK bike and it even has a nice reg number if you are interested in that sort of thing *** 1M
A lot of the nuts an bolts are non original, short rear guard, poor chrome on the rims if I remember correctly etc etc, but there aren't too many UK bikes about.
