Southern 100 Solo champion Michael Dunlop gained some valuable data from his Hawk Racing BMW as he builds towards the Ulster Grand Prix in August.
The Ulster rider romped to a four-timer on the S1000RR and won the feature Manx Gas Solo Championship race for the third time in commanding style from Silicone Engineering Kawasaki's Dean Harrison.
Dunlop, who will renew his rivalry with Isle of Man TT adversary Ian Hutchinson at Dundrod from August 10-13, ran into some braking issues with the BMW, but the 27-year-old dominated all four Superbike races nonetheless.
“The Solo Championship is the one people come here to win,” said Dunlop, who set his personal best lap of the Billown course at 114.099mph on his way to victory in the feature race.
“I had a good first and second lap, the bike was fantastic. Thanks to Steve, Mark, Tommy and Stuart at home and all of my own sponsors too. I did struggle with the brakes, but it wasn't anything major.
“I haven't rode that bike since the TT and I enjoy riding it. It was good to be back on board and to take the third win.
“When we heard the Senior race was to be re-scheduled we tried something different with the bike – it didn't make the difference, but at least we now know this for future races,” he added.
“I'm really comfortable on the big bike and to come away with four wins is great.”
