Ending a victory drought dating back to 2019 in last year’s TT with a brace of wins in the Superstock class, Harrison came out of the blocks swinging on Tuesday evening.

Harrison posted a 133.925mph lap on his Superbike in the opening session, and maintained that pace on Wednesday with a 133.712mph effort.

The Honda rider looked untouchable in the opening Superbike/Superstock session on Friday morning, posting a 134.877mph lap on his Superbike.

He concluded big bike qualifying in Q5 with a week-best of 135.484mph on his Superstock-spec bike, ahead of the opening race for the class on Saturday.

Harrison’s best lap of practice week came on his final lap of the session, meaning he was flagged into pitlane before the start/finish line having been out on the course when the chequered flag was flown.

Therefore, Harrison was likely looking at a lap record-threatening 136mph effort.

Fourteen-time TT winner Peter Hickman struggled on his Superstock-spec BMW, and encountered numerous issues on it in final practice.

Hickman posted the outright lap record of 136.358mph on a Superstock bike in 2023.

In Superbike trim, Hickman looked more competitive, posting a best of 132.712mph on Friday on his 8TEN Racing BMW.

Josh Brookes was third overall in Superbike with a 132.22mph set in the afternoon session.

Michael Dunlop was fourth in the Superbike standings on his Hawk Racing Honda, having looked much more comfortable on it.

He managed a 132.149mph on Friday, while John McGuinness was impressive in fifth on a 130.903mph on the Honda as he gears up to begin his 30th anniversary at the TT.

Racing begins on Saturday at 10:45am with the three-lap Superstock race.

There was to be a Sidecar race, but the class was suspended on Thursday from the rest of the event following a serious incident for the Crowe brothers on Wednesday evening.

The final Supersport and Sportbike session of qualifying week is due to start at 3:15pm local time.
