1966 Triumph Bonneville T120TT Special
We are really pleased to offer this outstanding and highly collectable 1966 Triumph Bonneville T120TT Special
1966 Factory Built Racing Motorcycle
The TT Special was a factory racer intended for competition in the US TT Steeplechase events and was sold on both the west and east coasts of the USA.
The T120C/ TT was produced in limited numbers from 1963 to 1967 so they are all very rare
Matching frame and engine numbers authenticated stamping from the ‘Guru’ Charles Rising.
We have the extract from the Works records and the build of this bike
Manufactured for five model years (1963-1967), Triumph’s fire-breathing TT Special is one of the world’s most famous high performance 650cc production-racing motorcycles.
From its introduction in early 1963 through the early 1970s, it won more American TT Scrambles races than any other machine, perhaps more than all other big-bore bikes combined.
It was also a feared drag-strip competitor.

Approximately 500 T120C stamped TT Specials were built in the first two batches.
