The 1947 Isle of Man Tourist Trophy was the first race festival since 1939 due to the interruption of World War II. With the restart of racing, the ACU decided to add three Clubman-class races for production machines in Lightweight, Junior and Senior categories, making the festival a six-race event.[1]
Harold Daniell won the Senior TT at 82.81 mph (133.27 km/h) on a Norton and the Norton team were to dominate the Senior race until 1954.[2] Speeds were somewhat lower than the pre-war races due to the low quality "pool" petrol available, and it would be another three years before Daniell's 1938 lap record was broken. Superchargers were banned for motorcycle racing from 1946, so that may have reduced speed too.[3]
This was an early race appearance for the E90 AJS Porcupine, ridden to ninth in the Senior by Les Graham.
