Reg Armstrong was born in a nursing home at 37 Lower Leeson Street, Dublin, on September 1, 1928. Armstrong did not have a privileged background but, his father started a successful motor factoring business in Dublin and supported his early motorcycle racing as much as he could. A cousin, Harry Lindsay taught him to ride during the Emergency and both rode 16H Nortons. Both joined the Irish Defence Forces, with the petrol ration a prime consideration.
Racing career
In 1946, Armstrong rode a pre-war Norton Manx at the Bangor Castle races in Northern Ireland. His was fifth in his second race, a handicap event, the Mid-Antrim 150, and then failed to finish at the Skerries 100. He put in an entry for the 1946 Manx but was refused as his 18th birthday was on the same day as the race. He borrowed a 500 cc engine and put it into his Norton, and entered the 1947 Senior Manx race without success. In the 1948 Skerries 100 he rode a Tom Arter AJS 7R to success, boosting his confidence enough to purchase a Triumph GP, with the help of his cousin Harry. He set fastest lap at the Cookstown 100 on that Triumph, at 74.79 mph, and at the 1949 Cookstown 100 raised it to 75.84 mph. AJS soon invited him to ride an AJS Porcupine at Ansty, and he managed to come fourth. AJS then signed him for the inaugural 1949 Grand Prix motorcycle racing season. Armstrong took fourth in the Swiss Grand Prix, fifth at Belgium, fifth in the Netherlands, third at the Ulster Grand Prix, sixth at Monza, and crashed at Silverstone. Freddie Frith was 350 cc world champion, with Armstrong finishing in second. At the 1950 Isle of Man TT Armstrong came sixth in the Senior TT on a Velocette. He came sixth in the 500 cc class, and seventh in the 350 cc class for the 1951 Grand Prix World Championship, and was then offered a place for the 1952 season on the Norton team. Armstrong won his first ride for Norton, the 500 cc class in the Leinster 200. He then won the German Grand Prix, and the Isle of Man Senior TT. It was Armstrong's most successful season so far, coming third in the 500 cc 1952World Championship, and second in the 350 cc. In the Republic of Ireland, Reg was now the agent for NSU and Honda. From 1953 to 1955, Armstrong rode successfully for Gilera and NSU. In 1953 he came second on a Gilera in the 500 cc class, and second in the 250 cc class on an NSU. In the 1954 he came fifth on a Gilera in the 500 cc class, and ninth in the 250 cc class on an NSU. In 1955 he came second on a Gilera in the 500 cc class. In the 1956 Grand Prix motorcycle racing season he came fifth on a Gilera in the 500 cc class, but growing business interests demanded more of his time and he announced his retirement from motorcycle racing.
Post racing career
In 1962, Honda asked Armstrong to become their racing team manager. They won three World Championships that year and two more the following year. By now, however, Armstrong's Ringsend plant ceased assembling NSUs and changed over to Opels, Armstrong now being the Irish agent for them. In 1964 Reg tried his hand at car racing driving with limited success. He became a good clay pigeon shooter, representing Ireland in the 1978 World Championships, held in Korea. In November 1979 the 51-year-old Reg died in an accident while returning to his Ashford home.
