The Triumph 6/1 is a motorcycle that was made by Triumph at their Coventry factory from 1934 to 1936. Designed by Val Page, the 6/1 was the first Triumph motorcycle to use a parallel-twin engine. A sidecar-equipped 6/1 won a silver medal in the 1933 International Six Days Trial and went on to win the Maudes Trophy for 1933. The 6/1 was a commercial failure, selling fewer than 600 in two years on the market.
