In terms of race victories, the Northern Irishman moved one win ahead of his illustrious uncle Joey with a record-breaking 27th triumph on his Paton machine.
After winning Saturday’s Supersport race and matching the all-time record, the 35-year-old was denied what appeared to be a surefire victory in Sunday’s Superbike race due to a problem with his visor.
Over a fifteen-year span, Dunlop has amassed his achievements in four distinct classes using equipment from six different manufacturers.
In the Supertwins, the Ballymoney rider put on a commanding performance, taking the lead and winning by 20.4 seconds.
Dunlop’s lead over the pursuing pack was 10 seconds after the first lap, courtesy of a lap of 121.044 mph. By the end of his second circuit, he was 12 seconds clear of Hickman, the closest competitor, and extended his lead even further with a lap of 122.434 on the final lap. With this victory, Dunlop now has four Supertwins wins under his belt.
