It was in a 1969 Cycle edition that they described the '67/68 650 Bonneville as "One of the best big bikes ever made. Smooth, fast and classy. Starts easily, hangs in there, even sounds good." The world already knew how good these bikes really were, Cycle simply reinforced us all. However, we indeed know much less about the supply chain story of the 1974 750 T140V motor given that the Triumph factory was locked in February of that year. We do know about its technical specification, however, as they had a 76mm bore with a 82mm stroke for 744cc (from 71x82 for 649cc) and a welcome 5-speed. Just how much horsepower resulted from the switch to 750cc is hard to fathom for it was seldom if ever published. In 1971 the 650 was quoted at 50 horsepower at 7,000rpm. A big enough beginning for a healthy flat track racing motor, perhaps.
Triumph Motors factory participation in flat track racing is legendary and diverse and goes back to just post-WW2. Today the record books are voluminous and without enough room to mention one famous name it would be simply unfair without mentioning all of them. Suffice to say, the Triumph twin motor in a variety of frames over the years was masterful, inspirational and available.
Thus, we can offer this 750 Triumph flat tracker as a celebration of that success without knowing very much about the bike itself beyond the basics. Just who built and raced it is a mystery. Clearly, it's not a professional effort, more a good homebuilt, farm field or county fair racer, perhaps. It is sold with no guarantees as its condition.
