Dean Harrison Wins RL360 Superstock TT with Career-Best 135.692mph Lap – First TT Victory Since 2019 and Honda’s First Superstock Win Since 2014
Dean Harrison (Honda Racing UK) delivered a commanding performance to win the RL360 Superstock TT at the 2025 Isle of Man TT, marking his first TT victory since the 2019 Senior TT. In a thrilling two-lap battle shortened due to weather delays, Harrison overcame early leader Davey Todd (Monster Energy by 8TEN Racing BMW) and crossed the line with an 11.6-second margin, setting a personal best lap of 135.692mph—one of the fastest ever in Superstock TT history.
This is Harrison’s first Superstock class victory, and it ends Honda’s 11-year drought in the category, their last win coming in 2014.
Tight Early Battle Between Todd and Harrison
Originally scheduled for 10:45 a.m., the race was delayed due to weather and shortened from three laps to two. Davey Todd took the early initiative, holding a slim 0.2-second lead over Harrison at Glen Helen. James Hillier (Muc-Off Racing Honda) followed in third, 5.3 seconds behind, with Nathan Harrison (H&H Motorcycles Honda) another 1.2 seconds back.
Michael Dunlop (MD Racing BMW) was fifth early on but moved up to third by Ballaugh. Hillier and Nathan Harrison both dropped a place, while Dom Herbertson (HRRC/Adam Hewitt Ltd Honda) climbed to sixth.
At Ramsey Hairpin, Todd stretched his lead to 2 seconds, but Harrison began his response soon after. Dunlop maintained third but was 13.3 seconds off the lead.
Harrison Charges to Victory with Blistering Final Lap
Todd completed the first lap with a speed of 133.712mph, maintaining a narrow lead, while Harrison clocked 133.658mph, just 0.4 seconds behind. Dunlop held third with a 131.061mph lap.
On lap two, Harrison surged ahead at Glen Helen with a 2.3-second lead, as Todd, encountering traffic, began to lose pace. The gap widened further at Ballaugh and Ramsey Hairpin, reaching 5 seconds, and nearly doubled by the Bungalow.
Harrison sealed the race with an incredible 135.692mph final lap, a career best, to take a dominant win. Todd, despite early control, had to settle for second with a 134.077mph lap. Dunlop, with 134.081mph, completed the podium and tied John McGuinness with his 47th career TT podium.
