The event saw adverse weather conditions which caused many delays and the cancellation of the second Supersport race.[1]
Just like 2016, the solo classes were marked by an intense rivalry between Michael Dunlop and Ian Hutchinson. This rivalry culminated in the 2017 Senior TT, won by Dunlop,[2] while Hutchinson suffered serious leg injuries in a race-stopping crash in the mountain section.[3] In the end, Hutchinson and Dunlop left the island with 2 TT wins each.
23-times TT winner John McGuinness was a major absentee due to career-threatening injuries suffered at the North West 200 a few weeks prior.[4]
Guy Martin made a high-profile return to the event, but suffered a high speed crash in the Superbike TT, and withdrew from the Senior TT.[5] He took second place in the TT Zero, his only race-finish of the week.
The event was marred by the deaths of 3 competitors: Davey Lambert,[6] Jochem van den Hoek,[7] and Alan Bonner.[8]
