Senior TT

The Senior Tourist Trophy is a motorcycle road race that takes place during the Isle of Man TT festival; an annual event at the end of May and beginning of June. The Senior TT is the Blue Riband event of the festival and takes place on the Friday of race week. The Marquis de Mouzilly St. Mars trophy is now presented annually to the winner of the Senior TT race. The event was part of the FIM Motorcycle Grand Prix World Championship during the period 1949-1976 before being transferred to the United Kingdom after safety concerns and run by the FIM as the British Grand Prix for the 1977 season.Guinness Motorcycle Sport Fact Book by Ian Morrison pp120 (1991)(1st Edition) Guinness Publishing The Bath Press ISBN 0-5112-953-6

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 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.
