Dean Harrison bagged his first Senior TT win on the Isle of Man today after Peter Hickman’s BMW began to fail on lap five and a near-18s lead was turned into a 53s deficit at the end the six-lap clash with Conor Cummins closing fast in third place.
Hickman was unable to use the hybrid Superstock/Superbike with which he won the Superbike TT on Saturday after scrutineers stripped his race-winning Superstock S1000RR down to nuts and bolts last night, so he was forced to use the full Superbike on which he hadn’t completed many laps.
It had been a two-horse race from the off but Hickman superiority on the run from Ramsey to the Bunglow had been responsible for over half of the 17s lead the Smiths Racing rider had built up by the end of the fourth lap.
But disaster struck as Hickman ran out to Glen Helen on lap five as his bike began to overheat and over 11,000rpm it began to throw water out so Hickman had to throttle it back and just try to keep Milenco by Padgetts Honda man Conor Cummins behind him.
At the end, Harrison was 53.062s ahead of Hickman who, in turn, was only 5.817s ahead of Cummins with Michael Dunlop a further 27.830s further back.
James Hillier - who had a nightmare first lap - took fifth place by just 2.568s from Davey Todd on the second Milenco by Padgetts Honda.
Veteran Michael Rutter was three minutes behind the leader in seventh with Jamie Coward, Brian McCormack and Dominic Herbertson completing the top ten.
Hickman and Harrison had opened a five-second gap over Cummins as they raced to Glen Helen on lap one with Dunlop just behind and Rutter in fifth.
The pair were only split by two-tenths at Ramsey but on the run to the Bunglow, Hickman pulled a second on Harrison which set the precedent for the rest of the race before Hickman.s bike went sick.
An opening lap of 134.28mph saw Hickman with a 2.209s lead on the end of lap one but Harrison hauled him back to a 1.990s advantage by Ballaugh on lap two. David Johnson clawed his way up to fifth place before retiring at the Bedstead and Honda team-mate Ian Hutchinson also retired on the same lap.
By the Bungalow, Hickman was 6.524s in the lead as Todd replaced Johnson in fifth place,. Hillier was recovering from his first-lap disaster and was slowly making his way back into the top ten.
On lap three, Hickman was 10.034s ahead at Glen Helen and increased that to 12.298s at the Bungalow. As they pitted on lap four, the lead was 17.683 but then it was disaster for Hickman as his BMW began to overheat and at Glen Helen on lap five the lead was less than eight seconds.
At Ballaugh, it was 1.1s and by Ramsey, Harrison was past and 7.877s in the lead. The Bradford man never looked back and added the Senior trophy to his cabinet. Hillier, meanwhile, took over from Todd in fifth place but at Ramsey on lap six, Todd was back in front.
Howveer, Hillier got the hammer down and managed to pull back the lead to cross the line in fifth place.
John McGuinness was forced to retire the Norton on lap one.
