The 700 Interceptor introduced in 1960 was a modified version of the company's 692 cc (42.2 cu in) Constellation model.

They had twin carburettors, except for some early bikes, a factory lightened and balanced crankshaft, hot "R" cams, Lucas racing magneto with manual advance and a few other weight saving modifications compared to other Royal Enfield models.

A total of 158 692 cc Interceptors were made as per the Redditch factory despatch ledgers held by the Royal Enfield Owners Club in the UK.

The US models received a new chrome tank, a new seat, instrument mounts, handlebar, and mudguards.

The CB points were moved to the end of exhaust camshaft and the timing cover was redesigned accordingly.

The modern bike was unveiled by Royal Enfield CEO, Siddhartha Lal and President, Rudratej Singh.

The teardrop tank features traditional Royal Enfield badges and a Monza-style fuel cap.

The UK weekly Motor Cycle News reported in November 2018 that Royal Enfield has just produced a "concept bike" that echoes a much earlier model.
