The Triumph TR5T was a motorcycle from the vehicle manufacturer Triumph . The Enduro was marketed as "Adventurer" in Great Britain and as "Trophy Trail" in the United States. The model was designed for road and light to medium-heavy off-road use.

Model history

The development of the TR5T was preceded by efforts by the US subsidiary Triumph America to bring a new competitive enduro motorcycle onto the market.

Series production in Meriden began on the basis of the frame and chassis of the BSA B50 MX . The engine with a 28mm single AMAL carburetor was the same as in the Trophy 500 . The motorcycle weighed just 134 kg and had an aluminum fuel tank as well as chrome-plated fenders and a chrome-plated lamp housing, which is typical of the period. In September 1972, the TR5T was presented to the press in Southern California.

Since the series machine did not seem powerful enough and the headquarters in Meriden showed no interest in increasing the performance, the Americans built a modified version of the TR5T around Bob Tyron. In this way, twelve handcrafted machines for competitions in the USA were created. The 48th International Six Days Trial in 1973 in Dalton , Massachusetts only brought Triumph America 34th place among the 50 participating manufacturer teams in the brand classification. The drivers were Dave Mungenast, Ken Harvey and John Greenrose. The performance of the technically outdated engine was not enough for a better result.

The production period of the series machine only extended from November 1972 to November 1974. The TR5T came too late to be a sales success for Triumph. Japanese manufacturers were already pushing their way onto the market with visually and technically more modern enduros. The unreliable Lucas electrical system, the lack of fifth gear and the unbalanced design prevented market success. In 1974 there were bankruptcies, strikes and plant blockades. When production in the Triumph workers' cooperative was resumed in 1975, the 500 cc Twins fell out of production.

It wasn't until 1980 that an enduro was added to the Triumph program again with the Tiger Trail .

The model name "Adventurer" was revived in 1996 with the Adventurer 900 .
