Royal Enfield Continental

248cc ohv single || 320lb || 65mpg || 80mph || 1962-67

Restyled version of the Crusader, with more power, vibration and oil leaks. It came with the five-speed gear cluster and replaced it with a four-speed set. With semi-racer styling on the GT model, it was a bit of a stunner but wasn’t a motorcycle you would want to ride a long way unless you are extremely flexible or have a masseuse on hand. Teenage buyers loved it. The name lives on in the current new Indian offerings, which are easier to live with.

Prices: low £3000 || high £5500
