Fast, brutal twin in pre-unit form until 1961, which maxed out in the late sixties, when handling was a touch dodgy rather than suicidal. Used to the full, the vibes shook, split and broke the cycle parts, whilst engine life could be less than 10,000 miles…though much sought after, one of the milder Triumphs is much more useful for general riding. Some really nice and nasty bikes out there. Also single carb, Trophy version.
