[edit] Engine capacity

The 1911 Isle of Man TT was the first time the Senior TT race took place and was open to 500 cc single-cylinder and 585 cc twin-cylinder motorcycles. It was won by Oliver C Godfrey, riding an Indian, at an average speed of 47.63 mph for the 5 laps of the Snaefell mountain course that was in use for the first time that year. The 1912 event was the first to limit the Senior TT to only 500 cc machines and this engine capacity prevailed until 1984.

The engine capacity has been modified from the usual (up to) 500 cc and is now (up to) 1,000 cc, though 1,000 cc machines were permitted in 1985 and 1986, 1,300 cc in 1987, 1988 and 1989, and 750 cc in 1990-1998.
