The TR6 Trophy is a motorcycle that was made by Triumph, in Meriden, from 1956 to 1973, when it was replaced by the five-speed 750-cc Triumph Tiger TR7V. The model was introduced in 1956 and named the TR6 Trophy-bird, borrowing its name from the Thunderbird model.[5] The model used the same engine as the T110, but with the new “Delta” alloy cylinder head. The cast iron barrel was retained, but painted silver. The engine used 8.5:1 compression ratio and developed 42 bhp. The power delivery made the mount ideal for off-road competition, for which the model is well known. The competition variant, popularly known as the “desert sled”, won numerous competitions throughout the late 1950s and 1960s. Steve McQueen’s fondness for the model is well known, as is his participation in the 1964 ISDT on a TR6 Trophy. https://en.wikipedia.org/wiki/Triumph_TR6_Trophy
