The 2027 Isle of Man TT will move its six-lap Senior TT away from the traditional closing slot. The race is scheduled for Friday, June 11, making it the penultimate race day of the meeting. Sidecar and Sportbike races will bring the event to a close on Saturday, June 12—the same day that organisers are retaining as a contingency opportunity if weather affects the programme.

The change comes ahead of the 100th running of the Senior TT, after two heavily disrupted editions. Poor weather resulted in the race being cancelled in 2025. In 2026, the Senior did start, but red flags stopped it after one lap; it was not restarted and a result was declared. Organisers are therefore placing the centenary race on Friday while leaving the final Saturday available for possible timetable recovery.

Nine races and revised categories

The 2027 programme begins on Saturday, June 5, with the six-lap RST Superbike TT. Supersport race one follows on Sunday, June 6. Tuesday, June 8, is scheduled for race one of the Superstock and sidecar categories. On Wednesday, June 9, the second Supersport race will be followed by Sportbike race one. The Senior TT takes place on Friday, before the final Saturday programme.

The schedule contains nine races in total. One notable change is the return of sidecars, which were suspended from the 2026 TT after a series of major accidents. Their 2027 comeback will operate under new rules intended to make the category safer, more sustainable and more competitive. At the same time, Supertwin motorcycles will be absent for the first time since 2012, with the class transitioning fully to Sportbike machinery.

Why the organisers changed the timetable

Paul Phillips, Head of Motorsport for the Isle of Man TT Races, said the revision is not a return to the schedule used before 2023. He said the post-2023 format had created stronger opening and closing weekends, offered more racing during the week and gave visitors greater choice about when to attend. Across the four TT events in which it operated, he added, it had also helped attract more fans and deliver greater economic benefit to the Island.

For 2027, Phillips said reducing the number of Superstock races from two to one will give the remaining Superstock race and both Sportbike races greater substance. The change is also intended to create more recovery time and better protection around the Superbike and Senior TTs. He described the new arrangement as an evolution that retains the two-weekend structure while giving each race day a clearer purpose.

The centenary Senior TT will consequently be treated as more than a standalone six-lap contest. According to Phillips, Friday’s programme will be built around the historic occasion, with attention also directed to the riders, motorcycles and performances that have shaped the race’s place in TT history.
