Defending champion Cameron Beaubier (Monster Energy/Yamalube/Yamaha Factory Racing) dominated Sonoma Raceway’s seventh round of the 2017 MotoAmerica Championship, claiming Super Pole and taking two commanding race wins.

Race one saw Beaubier navigate his way to a 6.144s victory over Tony Elias (Yoshimura Suzuki Factory Racing), who edged out Josh Hayes (Monster Energy/Yamalube/Yamaha Factory Racing) for the runner-up position.

Jake Lewis (Ecstar Suzuki) was fourth, as Mathew Scholtz (Yamalube Westby Racing Yamaha) finished a distant fifth, almost 20 seconds behind the top four.

It was repeat of results in race two with Beaubier leading Elias – who continues to control the championship by 70 points – and Hayes to the chequered flag, this time crossing the line 7.222s ahead of the field. Shcoltz and Lewis traded positions in the second outing to finish fourth and fifth respectively.

Championship contender Roger Hayden (Yoshimura Suzuki Factory Racing) endured a weekend he’d rather forget, lodging two DNF results at the Californian circuit.

Australian Alex Phillis (MV Augusta) contested the Supersport category, racing to a credible 12th in race one before bowing out of the second outing, ultimately recording a DNF.

The next round of the MotoAmerica Championship is scheduled for Pittsburgh, Pennsylvania, on 25-27 August.
