Which rider has the most Isle of Man TT wins?
Answer
Michael Dunlop
Which rider has the most Isle of Man TT wins? The correct answer is Michael Dunlop.
Michael Dunlop became the Isle of Man TT’s most successful rider in 2024, when he exceeded his uncle Joey Dunlop’s long-standing record of 26 victories. He finished that year with 29 TT wins.
Dunlop added four more victories at the 2025 TT, bringing his career total to 33 wins. This extended his lead over Joey Dunlop, who remains second on the all-time list with 26 victories.
The record includes wins across several TT categories, including Superbike, Supersport, Superstock and Supertwin races. Dunlop’s achievement is especially notable because he comes from the same celebrated Ballymoney racing family as Joey Dunlop and other major road racers.
