The 2005 Isle of Man TT Festival was the 98th run and took place between Saturday 28 May and Friday 10 June on the 37.73 mile (60.72 km) Mountain course.
Bad weather meant that the Superbike race was held over until Sunday (5 June).
John McGuinness won the Superbike TT and Senior TT, and was the only competitor to win multiple races that year.
Three competitors died during the event: Joakim Karlsson, Les Harah and Gus Scott.
[1][2][3] Gus Scott, a rider-journalist participating in his first TT, died after colliding with Kirk Michael resident and marshall April Bolster, who was crossing the road to attend to another rider.
