a final attempt with the 692cc Interceptor in 1960-1961, followed in 1962–1968 by the 736cc Series I and Series II Interceptors. Made largely for the US market, it sported much chrome and strong performance, completing the quarter-mile in less than 13 seconds at speeds well above 175 km/h (105 mph). It became popular in the US, but the company was unable to supply this demand, which accelerated the demise of this last English-made Royal Enfield. The Redditch factory ceased production in 1967 and the Bradford-on-Avon factory closed in 1970, which meant the end of the British Royal Enfield. After the factory closed a little over two hundred Series II Interceptor engines were stranded at the dock in 1970. These engines had been on their way to Floyd Clymer in the US; but Clymer had just died and his export agents, Mitchell's of Birmingham, were left to dispose of the engines. They approached the Rickman brothers for a frame. The main problem of the Rickman brothers had always been engine supplies, so a limited run of Rickman Interceptors were promptly built. Enfield Indians From 1955 to 1959, Royal Enfields were painted red, and marketed in the US as Indian Motorcycles by the Brockhouse Corporation, who had control of the Indian Sales Corporation (and therefore Indian Motorcycles) and had stopped manufacturing all American Indians in the Springfield factory in 1953. But Americans were not impressed by the badge engineering, and the marketing agreement ended in 1960, and from 1961, Royal Enfields were available in the US under their own name. The largest Enfield 'Indian' was a 700 cc twin named the Chief, like its American predecessors.
