A few pics of the new 1955 T100R from clips found in Motorcyclist and CYCLE magazines. The small size of the pictures and the low quality of the magazine print is the reason begind the low resolution. Apparantly very little information or pictures have survived of this model.
From the "Triumph Racing Motorcycles in America" book.
I've identified this bike as the later 1957-1959 T100RR as found in a 1960 issue of Hot Rod Magazine. The bike is easily identified by the 1957 type lower fork sliders and the cylindrical oil tank as opposed to the standard type used on the T100R. Another difference I'm seeing is that the 1955 T100R has the wide TR5 gas tank and the later T100RR has the smaller type. This machine looks almost box stock with the exception of the custom paint job and seat as well as a standard type left side exhaust pipe. In my opinion this is one of the coolest Triumph's to have ever been made available directly from the dealership and this mildly customized drag bike is the ultimate!
