The great escape artist

It’s sometimes difficult to remember that when these bikes were new they were bought to be ridden all the time and thrashed off-road too.

THE TR6 WAS born for the USA and enjoyed its moment of glory in an American movie.

The Thunderbird was a Harley-beater in terms of performance, but its all-iron engine was really designed for the street.

In competition, everything from scrambles to the Clubman’s TT in the Isle of Man, Triumph riders relied on the all-alloy 500s which were light and fast.

However, the 500s were underpowered for the West Coast, particularly for desert racing.
