Main article: Royal Enfield Interceptor
During the onslaught of the Japanese motorcycle manufacturers in the late sixties and early seventies, the English factories made a final attempt with the 1962–;1968 [17] series I and Series II. Made largely for the US market, it sported lots of chrome and strong performance, completing the quarter mile in less than 13 seconds at speeds well above 175 km/h (105 mph).[18] It became very popular in the US, but the classic mistake of not being able to supply this demand added to the demise of this last English-made Royal Enfield.[19]
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.[20]
As far as the motorcycle brand goes, though, it would appear that Royal Enfield is the only motorcycle brand to span three centuries, and still going, with continuous production. A few of the original Redditch factory buildings remain (2009) and are part of the Enfield Industrial Estate.
