DEAN Harrison claims that his hard work and that of his team have resulted in the Bradford rider's second victory in the Isle of Man TT.

The 29-year-old notched a record-breaking victory in yesterday's Monster Energy Supersport race.

After leading from start to finish, and enjoying a maximum advantage of 21 seconds, the Silicone Engineering Kawasaki rider finished up winning by 18.5 seconds over Peter Hickman (Trooper Triumph by Smiths Racing), with fellow Englishman James Hillier (Quattro Plant JG Speedfit Kawasaki) in third.

Harrison's best lap speed of 129.099mph was just outside the record for the class set by Michael Dunlop on Monday but his advantage of 8.749sec at the finish was a record.

Dunlop, who finished fifth, was lying second when he was penalised 30 seconds for speeding in the pit lane after his refuelling stop at the end of lap two.

But even though won the first middleweight race on Monday, it is doubtful whether Dunlop would have been able to match Harrison, who had an eight-second lead by the end of the second circuit.

Harrison, whose previous TT win came in the 2014 lightweight category and had finished second and third earlier in the week, said: "I got the head down from the start, built up a bit of a lead and kept pushing. I'm over the moon.

"We've been trying, trying, trying all week and now all our hard work has paid off."

As he has done for most of this week, Harrison led through Glen Helen on the opening lap, with his lead over Dunlop being 1.8sec.

An opening lap of 128.188mph gave Harrison a 3.6sec lead over Dunlop, with Hickman third a fraction behind.

As they swept through Glen Helen on the second lap, Harrison's advantage had stretched to 4.5sec, and it was 8.3sec as he came into the pits.

Dunlop's penalty meant that Harrison's advantage over Hickman shot up to 18.3sec, and he eventually won by 18.5sec.

Bingley's Ian Hutchinson (Honda Padgetts) was 11th and Adrian Harrison (Honda Martin Smith Ground Works) was 30th.
