Spectacular! I owned a '75 850 Commando Interstate while living in southwest Germany quite a few years ago and absolutely loved it despite the Amal carburetors and Lucas 12 volt positive ground electrical system.
During the summer of 1980, I and two friends (riding a Gold Wing and BMW 750), rode from Germany, through Belgium, crossed the channel to Dover, then wandered through southern England, up through Wales to Heysham, took the ferry to the Isle of Man (for the Manx Grand Prix), spent some 10 days on the island, then returned via the Lake District, down the eastern coast to Felixstowe, back across the channel, through Belgium and home to Ramstein.
It was an extraordinary trip and, surprise of surprises, the Norton was the only bike that made the trip without a single incident. It was even mentioned on Manx Radio. Can it get any better than that?
My biggest mistake was selling it but I did get more than I paid for it. Ah well.
Headed back to the Isle of Man in September.
My ancestors came from the IOM so it's rather like going home.
