does anyone know anything about the display team that used to do events like the royal cornwall show ...I think ive found one of the bikes and wandered if I could find out some history too it
Do you mean the White Helmets? If so, there were a few clips included in Henry Cole's recent programme on the history of Triumph and my recollection is that Les Harris (Newton Abbot) kept making special Triumph T140s for the Army team long after production for the general public had ceased.
Do a bit of Googling e.g. https://www.bbc.co.uk/news/uk-england-dorset-42011143
bought an xr250 on ebay from torquay and the seller thought it was from a display team and im sure I monce saw a display at royal cornwall where they were riding them
