The TT returned to action last year having been forced to miss 2020 and 2021 due to the COVID pandemic.
The 2023 event is set to be the biggest in TT history, with two more races being added to an already packed schedule in the form of a second Superstock and Supertwins contest.
In total, there will be 10 races staged, with the first Supersport contest kicking off race week on Saturday 3 June.
As well as new races, there have been several tweaks to the regulations for 2023.
Here is everything you need to know about the 2023 Isle of Man TT.

What’s new for the 2023 Isle of Man TT?
The biggest change for the 2023 Isle of Man TT is the addition of two races.
Where traditionally the Superstock and Supertwins class had just one contest each during race week, both categories now have a second. This brings the total number of races to 10.
The opening race of 2023 will not be the first Superbike contest, with the big bikes having their first outing on Sunday 4 June.
For 2023, the first Supersport contest will open race proceedings. As ever, the Senior TT closes out the week on Saturday 10 June – marking the first time the finale has been actively scheduled for the final Saturday of race week.
What are the new rules for the 2023 Isle of Man TT?
There have been several key rule changes made ahead of the 2023 Isle of Man TT.
The most significant is slick tyres being permitted for use in all classes for the first time. Prior to 2023, only the Superbike class could race slicks, with cut slicks mandated for Superstock, Supertwin and Supersport competition.
With tyre rule changes taking place in British competition and at world level, as well as the cost involved for manufacturers to get road-legal cut slicks homologated, full slicks have been permitted for all solo classes.
In the Superstock class, bikes with a displacement of above 1000cc are being allowed to race for the first time providing they have a control electronics unit fitted to ensure a balance of performance.
Previously, the fixed capacity for the Superstock class was 1000cc four-cylinder machines. But emissions law changes have forced manufacturers to push beyond this on their road bikes, hence the rule tweak.
The Supertwin class was tweaked in 2022 to allow 700cc machinery to race, albeit with a weight penalty. For 2023, the minimum weight limit for all eligible bikes will be 150kg to ensure parity.
How can I watch the 2023 Isle of Man TT?
The Isle of Man TT will be available to watch in a number of different ways for 2023.
After successfully launching its TT+ platform in 2022, and bringing live television coverage to the end for the first time, this will continue in 2023.
Every second of practice and race action will be available to stream on the TT+ Live Pass, which is available for a one-off payment of £19.99.
Coverage begins on Monday 29 May for the first practice session and will carry on through to the final race day on 10 June.
UK viewers who don’t have access to TT+ will be able to watch nightly highlights of practice and the races on ITV4 at 9pm, starting on Friday 2 June.
