Dean Harrison was on course for his second victory of the week at this year’s Isle of Man TT Races when he led the Milwaukee Senior TT halfway round the second lap only for a red flag to bring proceedings to a halt. 
 
The Honda Racing UK rider was over 14 seconds clear of Peter Hickman (Monster Energy BMW Motorrad by 8TEN Racing) as he was making his second ascent of Snaefell and was two seconds inside the outright lap record, but the red flag came out shortly afterwards due to an incident at the 11th Milestone. 
 
Getting underway at 6.25pm, Harrison led at Glen Helen on the first lap by 4.1s from Hickman and it was Ian Hutchinson (Team RST BMW) in third, 3.2s adrift. Josh Brookes (DAO Racing Honda) slotted into fourth, but Michael Dunlop MBE (MD Racing Honda) was only in fifth, albeit only three tenths of a second behind his fellow Honda rider as a good start by David Johnson (Platinum Club Racing Kawasaki) saw him in sixth. The gaps were tight as only two seconds covered sixth to 12th. 
 
By Ballaugh, Harrison’s lead over Hickman had increased to 6.7s and Brookes was up to third although his advantage over Hutchinson was only 0.086s. Dunlop was a further 1.5s behind in fifth as Jamie Coward (Rapid Honda by DriveLife) moved up to sixth. 
 
Through Ramsey for the first time Harrison had extended his advantage over Hickman to 7.8s with Brookes now 8.1s behind. He’d opened a small gap over Hutchinson though, the difference between the two riders standing at 1.5s. Dunlop remained in fifth, a second behind Hutchinson. 
 
Harrison continued to build on his lead up and over the Mountain and an opening lap of 135.166mph saw him head into lap two with a 12.4s advantage over Hickman (133.510mph). Brookes continued to hold onto third after lapping at 132.775mph but that closed him to within 5.6s of Hickman as Hutchinson (131.789mph), Dunlop (131.356mph) and Coward (130.005mph) completed the top six. 
 
Reaching Glen Helen for the second time, Harrison was continuing to press on with another strong sector, his lead over Hickman creeping up to 14.3s. Hickman had edged away from Brookes too, the gap now 9.4s as Brookes overhauled Dunlop on the road. Hutchinson, Dunlop and Coward were holding station in fourth to sixth. 
 
Only three seconds covered the five riders battling for sixth – Coward, Johnson, Nathan Harrison (H&H Motorcycles Honda), John McGuinness (Honda Racing) and Conor Cummins (Conrod’s Motorsport BMW) but at the head of the field Harrison was showing no signs of letting up. 
 
His lead had extended further at Ramsey to almost 15 seconds and he was on course to challenge Hickman’s three-year old outright lap record, but the race was stopped shortly afterwards and the race curtailed. 
 
Due to less than 50% of the race being completed the race could not be declared a result, therefore the Milwaukee Senior TT was rescheduled for 12:00 on Saturday 6 June.

Following the conclusion of the 2026 Isle of Man TT Races, Dean Harrison has been declared the winner of the Milwaukee Senior TT based on the positions at the end of lap one in Friday evening’s original race start.

After flying out of the gates, the Honda Racing UK rider pulled out a 14 second lead over the rest of the field over one lap, lapping at 135.166mph from a standing start. He had reached the Mountain section by the time of the red flag on lap two, having been on lap record pace throughout the run to Ramsey.

Harrison’s win moves him up to seven victories around the Mountain Course, putting him on par with Mick Grant, Wolfgang Kalauch, Michael Rutter, Tony Rutter. He also becomes a two-time winner of the Senior TT, and wins two races in a week for the second year in succession.

8TEN Racing’s Peter Hickman and DAO Racing’s Josh Brookes completed the top three, with the latter achieving his third podium result, and second in the Senior.

I’m absolutely ecstatic, I’m over the moon for me and for the team effort. To win not one but both the big bike races is something else. Unfortunately we didn’t get to have a proper go in the superstock race where we felt strong, but that’s racing, that’s the weather and that’s what makes the Isle of Man TT races as unique as they are. It’s not easy to earn the label as the toughest race in the world but that’s what this is and that means sometimes the weather takes over. The anticipation builds around a mixed schedule, the anxiety to go creeps in and the whole tension of the event is part of what makes it so special to race here and to win here. To be sat here holding one of the oldest trophies in motorsport on behalf of the team is an incredible feeling after such a testing week.

When I think back to the winter and how I was working with the team to turn the idea of a hybrid superbike into reality, I feel pride and relief that the idea worked and I was able to deliver. It’s a testament to the strength of the Honda Fireblade in standard trim and it gives us something really useful to build off going forward. I knew I was going to be fast, I was confident I could deliver and I did exactly that. We’ll keep the ball rolling and add to our successes.
