Triumph T100 Grand Prix for sale at Oley AMCA swap meet, 2012.

Triumph motorcycles was reluctant to enter the world of road racing - it just never interested Ed Turner. However, right after the war, a surplus of generator motors Triumph built for the Royal Air Force turned out to have the key ingredient to solving the Speed Twins over heating problem when highly tuned - a square all-alloy barrel and head. The first T100 to employ the generator top end was entered in the manx Grand Prix and took first place - raced by Ernie Lyons and built by Freddie Clarke. 


Triumph released a version of the bike for the years leading up to 1950. The Grand Prix (named after the race it won on the Isle of Man) had more success but when 3 machines were entered in the Senior TT, they failed to finish. Ed Turner's racing enthusiasm wained and the bike was discontinued in 1950 when a racing kit was added to anyone who wanted to build their own competition machine.
