Want to be an expert on Triumph’s 350 and 500 unit-construction twins? Here is everything you need to know about these classic machines.
Alongside the headline-grabbing bikes – the Bonneville and Trident – Triumph built a whole series of smaller 350/500cc machines, with all the style of their bigger brothers, but lighter in weight, easier to ride, and now cheaper to buy. The Triumph 350/500s played a key role in the company’s success through the 1960s, in North America as well as the UK. The range included everything from the original 350cc 3TA, a mild-mannered tourer, to the final Daytona Tiger 500 (a modified version of which won the Daytona 500 race in 1967), and the TR5T trail bike.
