apparently 1 of only 2 built like this in Oz. Not so sure about that - but the racing heritage has some truth. These bikes were turned into road-racing rockets in the US in the late 60's, just prior to the first H1R's coming out of the factory. Apparently they used to tune these little jiggers to pull 60hp at the back wheel !!!! FMD it would be peaky. But heaps of fun....
Anyway this Bighorn would be a bargain in anyone's language for $1800. Someone from here should buy it !!
