Keen motorcyclist Prince William, the Duke of Cambridge, attended the Isle of Man today to see the TT races first hand, as well as flagging off the TT Zero race and presenting the trophy to race winner Michael Rutter.

Rutter won the electric bike race with a new record lap of 121.824mph as he gave the Japanese Mugen team their fifth successive win, although the big talking point was the excellent showing of Daley Matheson on the University of Nottingham machine, which took second place with a 119.294mph lap – which was also inside John McGuinness’ outgoing lap record.

The rapid improvement in the electric bike technology could also be seen by the speed trap figures, with third placed Lee Johnston topping 170mph through the Sulby straight speed trap.

Earlier in the day Dean Harrison had taken his first win of TT2018 with victory in the second Supersport TT. The Yorkshireman had set an outright circuit lap record in Saturday’s Superbike TT, before retiring with mechanical problems, but he was finally able to stand atop the podium after dominating the four-lap 600cc race on his Kawasaki ZX-6R.

Peter Hickman (Triumph) and James Hillier (Kawasaki) rounded out the podium after Monday’s Supersport winner Michael Dunlop was handed a 30 second penalty for speeding in pit lane. That penalty moved him from second to fifth in the overall standings, with local rider Conor Cummins taking fourth in what has been a good TT for him so far.

Today’s action closed with the Lightweight TT, which was won by Dunlop on a Paton. The Northern Irish rider set another new lap record during the four lap race, which is for 650cc two-cylinder machines, with an average speed of 122.750mph on the way to his 17th career TT victory. Derek McGee and Rutter completed the podium finishers following the retirement of lightweight specialist Ivan Linton, from second place, on the second lap.

TT 2018 is due to come to a conclusion on Friday with the running of the second sidecar race and the blue riband six-lap Senior TT.
