Jack Marshall achieved Triumph’s first win in the TT (held on the St John’s short course) , beating Charlie Collier’s Matchless to win the 1908 TT by two minutes at an average speed of 38.7mph.
A Triumph also came third, ridden by Captain Robert Arbuthnot RN. Both rider and his motorcycle were sunk and lost at the Battle of Jutland in 1916.
Some rule changes were made by the organisers for the race - pedals were banned (not least because Charlie Collier, an experienced racing cyclist, had made good use of them during his 1907 TT win). Silencers became mandatory and were tested before the race. Fuel consumption was limited to 100mpg for the singles and 80mpg for the multi-cylinder bikes (from 90 and 75mpg in 1907).
