Josh Owens has taken his first Superstock victory of the year after beating points leader Ilya Mikhalchik by just 0.090secs.
From pole, Owens took the lead at the start but Mikhalchik was ahead by the end of the first lap and controlled the race until Lap Five when a charging Tom Ward hit the front.
Ward led until Lap 10 of the 15 but Owens, having dropped to fourth, was suddenly flying, moving from fourth to second and then putting a pass on Ward for the lead.
Owens looked to be in charge but behind, Mikhalchik had a second a wind and after passing Ward, set about catching Owens. Despite quickly catching his rival, he ran out of time to get past and had to settle for second at the flag.
David Allingham crossed the line third, with Matt Truelove fourth and Ward fifth.
