The2005 Isle of Man TT Festival was the 98th run and took place between Saturday 28 May and Friday 10 June on the37.73 mile (60.72 km)Mountain course. The first week (between 28 May and 3 June) is known as the practice week, before the real action was due to commence on 4 June. Bad weather meant that the Superbike race was held over until Sunday (5 June). There were only 7 races in this year because this was the first year the smaller 250 bikes & Production models did not race at the TT, instead they were replaced with Superbike, Supersport & Superstock races.

TheSidecar TT Race A, was supposed to be race 2 but due to inclement weather forced the postponement of the Superbike TT for 24 hours, the Sidecars became the first race.

John McGuinness won the Superbike TT andSenior 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 withKirk Michael resident and marshall April Bolster, who was crossing the road to attend to another rider. Bolster also died instantly.^[4]
