Metzeler National Superstock 1000 race winner David Johnson will further his forays into road racing after signing to ride for the legendary McAdoo Racing squad at this year's Ulster Grand Prix.

The Aussie, who was victorious last time out at Oulton Park in the BSB support-class race, made his Dundrod debut in 2010 with a more than respectable 127mph lap and is aiming for top-five results in 2012.

“I really wanted to get into a good team for 2012 and show what I can do at Dundrod. I’m really excited to be on the McAdoo bikes and I can’t wait to get started," he said, quite briefly for him.
