Triumph 5T & 5TA Speed Twin Parts
The Speed Twin is the machine that set the pattern every other British twin followed. The pre-unit 5T came first, the unit-construction 5TA replaced it in 1959, and the two are different motorcycles wearing the same name. Which one is on your bench decides most of what you order.
Obsolete Bike Parts holds 5T and 5TA parts alongside the Triumph 500 range they share so much with.
Pre-unit 5T or unit 5TA
The 5T has a separate engine and gearbox; the 5TA carries them in one casting from 1959. A good deal of the 500 twin parts list is common with the Tiger 100 in both eras, and some cycle parts run the full width of the range from the 5T to the T120. Frame and engine numbers settle it.

Across the range
