With continuing perfect weather and record laps, Dean Harrison of Silicone Engineering Kawasaki took his first win of the week with an 18.6-second victory over Peter Hickman in the Monster Energy Supersport Race 2. The Bradford rider broke the race record by 8.749 seconds in the process. Harrison battled Michael Dunlop for the lead throughout the first two laps, but Dunlop was assessed a 30-second penalty for exceeding the maximum pit lane speed of 60 kph and was out of contention for a third win.
In the single lap Zero Emission TT, Michael Rutter on the team Mugen TT Zero machine, became the first rider to clock a 120 mph-plus lap of the TT Course, taking the win. His Royal Highness, the Duke of Cambridge, flagged away Rutter on the start and later received his trophy from the Duke on the TT podium.
Afterward Rutter revealed that he had been feeling the pressure all week to deliver a result for the Japanese Mugen outfit. Splitting the placement of the two Mugen bikes, Daley Mathison on his University of Nottingham bike was only 24 seconds back.
The final event of the day was the Bennetts Lightweight Race. Dunlop took a record-breaking win in the Bennetts Lightweight TT on Wednesday afternoon at the Isle of Man TT Races fuelled by Monster Energy with the Paton rider smashing both the lap and race records on his way to his 18th TT win.
