New Zealand's Bruce Anstey has moved onto 11 Isle of Man TT wins after claiming his first success in the SES TT Zero race on the Japanese Mugen machine.
Anstey capitalised when team-mate and pre-race favourite John McGuinness ran into trouble, lapping at 118.416mph to wrap up the win by 25.4 seconds from Northern Ireland rider William Dunlop (Victory Motorcycles).
Anstey is now level on TT wins with Steve Hislop and Phillip McCallen following his win the much maligned clean emissions race, which only saw five finishers in total. McGuinness, who thinks the kill switch was activated on his machine, managed to get going again to cross the line in fourth.
Sarolea Racing pair Dean Harrison and Lee Johnston failed to even start the race.
Daley Mathison completed the rostrum places on the University of Nottingham-prepared machine for his maiden TT podium.
Race winner Anstey said: “I came across [John] McGuinness somewhere and saw he had stopped. I just kept going and I gave it a real good go from the start because I knew John would be absolutely flat-out from the off.”
Runner-up Dunlop, who sat out the earlier Supersport race due to a back injury he sustained after a crash in practice at Sarah's Cottage, was fastest through the speed trap at 159.8mph.
“It's been too long since we've been in here,” said Dunlop, who lapped at 115.844mph.
“The bike is nice to ride and I thought we'd have taken a bigger step forward from practice than we did, but I'm over the moon for the team because they've put a lot into this and they've travelled a long way to be here.”
A dejected McGuinness could not hide his disappointment afterwards.
“I pulled up coming out of Quarry Bends and it must have knocked the kill button when I landed somewhere,” he said.
“I got going again but it's so disappointing because it was close between me and Bruce. It's not been my week because I broke down on the 600.”
