The Ulsterman did so by setting a new unofficial lap record of 135.531mph, though because it was posted in practice it doesn’t count on the official statistics.
The current outright lap record belongs to Peter Hickman, who posted a 135.452mph average lap speed in 2018.
Officially, there are nine lap records, though three of which won’t be beaten in 2023.
Here are the current lap records for each class at the Isle of Man TT.
The outright lap record at the Isle of Man TT is an average lap speed of 135.452mph set by Peter Hickman in the 2018 Senior TT. The total lap time for that record around the 37.75-mile TT course is 16m42.778s.
Hickman did this on a BMW S1000RR run by the Smiths Racing Team on his way to victory in the 2018 Senior TT finale.
Hickman actually set a new lap record twice in that 2018 Senior TT, posting a 134.456mph effort on lap four of the six-lap contest.
This lap was marginally quicker than the outright lap record Dean Harrison set during the week’s Superbike TT race, which was a 134.432mph on a Kawasaki. That took the record away from Michael Dunlop, who posted a 133.962mph in the 2016 Senior on a BMW Superbike.
