Produced by Paul Wright from 1962 to 1965.
In December 1963 the address was
Silverstone Works, Whitfield, Brackley, Northamptonshire.
Later, the address is believed to have been 40 Rochford Road, Bishops Stortford, Hertfordshire.
Bodywork was by Chris Butler. Alloy tanks were offered as an option, as were Parkinson crankcases and Alpha crankshafts.
1964 Late in the year a road-racing model was added, this with its own Scorpion designed and made 246cc engine hung from a tubular spine frame. An attractive machine, a prototype GP5 was displayed at a trade show but did not achieve production.
1965 A Scorpion was ridden by Chris Cullen in the SSDT. A brochure was produced illustrating the GP5 roadracer and the Avenger 250 MX4 (coming soon). In addition to manufacturing motorcycles, the factory was also building Dr Who's Daleks. Scorpions were not exactly exterminated, but that year saw the end of the marque.
