Isle Of Man-Michael dunlop has ended a $38million contract because of a disagreement he had with management about….

Michael Dunlop added to his record tally of wins at the Isle of Man TT by securing victory in Saturday’s second Supersport and Supertwins races of the week.

Dunlop’s successes took his total number of victories at the event to 29 and completed the fourth four-timer of his career.

The 35-year-old has now won a remarkable 13 Supersport races, including three successive doubles on his Yamaha R6, and five Twins races.

Dunlop equalled his uncle Joey’s record of wins by winning last Saturday’s Supersport opener and moved ahead in terms of all-time race triumphs by taking a Supertwins success on Wednesday.

The Ballymoney rider competed in the Senior race later in the day, affording him the opportunity to equal Ian Hutchinson’s record of five wins in a week from 14 years ago, but retired on the first lap with a mechanical problem.

Dunlop won the Supersport race by 3.88 seconds from Honda Racing rider Dean Harrison, with Superstock race winner Davey Todd a further 2.3 seconds adrift on his Ducati V2.

The race was run over two laps rather than the initially scheduled four because of weather delays during the week and started two and a half hours late on Saturday at 13:00 BST because of damp patches on the course.

He followed that up with first place in the Supertwins, with the results taken from the end of lap one after the race was red-flagged on the second and final lap following an incident at Handley’s Corner.
