Triumph T100 Grand Prix 1949
We'd like to share some of theses pics with you.
Triumph might have been expected to play a major part in the war but the bombing raids on Coventry damaged the factory and it was only able to resume limited production during 1942 at a temporary premises in Warwickshire. Triumph intended to concentrate its military production on a 350cc machine based on the Speed Twin but the only model built in quantity was a 350cc single.
Production of the Speed Twin and Tiger 100 resumed in 1945 and these models were soon modernised with telescopic forks. Shortly after, Triumph staff realised that the leftover stock of cylinder barrels from an auxiliary generator unit Triumph had built for the Air Ministry during the war offered the potential to create a lightweight, high-performance Tiger 100. Specifically providing a means of curing the overheating , to which highly tuned Triumph twins were prone.
Prototypes were prepared by Freddie Clarke, a pre-war record breaker and one was entered in the 1946 Manx Grand Prix, ridden by Ernie Lyons. The model achieved a famous win ahead of the Manx Norton. The race machine produced between 25 and 30% more power than the sports roadster and went into limited production. The generator-based engine was housed in a rigid frame with Triumph's telescopic fork. A form of rear springing was offered by the Turner designed sprung-hub which provided a limited degree of movement but it was also prone to rapid wear, which could result in severe handling problems.
Despite this, in 1948 the GP model, as it was called, won the Manx Grand Prix again and over the next few years made its mark in road racing. It was phased out in 1950, making way for race-kitted versions of the T100, but it had already become part of the Triumph legend.
A speed hill climb at Shelsey Walsh was held on the day of the luncheon, at which Ernie put up t6he fastest time of the day on the same machine to make it double celebration. The meeting ran late and Ernie had to sit down to lunch still clad in his racing leathers!
