I saw one like that mid to late 90s in a bike dealer in Bradford, can't remember the name of it but it used to sit there in the showroom with no miles on it. They said it was the bosse's.
A friend works in a bike shop east coast America and has recommissioned a few of them from storage, he hates doing the carbs as they take so long to strip, clean and rebuild.
Very nice bike though especially in that colour.
