Ryuichi Kiyonari finished sixth overall last year

The HM Plant Honda rider cruised to victory in the first race with Gregorio Lavilla second and Glen Richards third.

He had a harder battle in the second race but was able to come home ahead of Michael Rutter and Lavilla.

Reigning champion John Reynolds, who is racing a month after badly breaking his leg, took two ninth-place finishes.

Pole-sitter Leon Haslam fell off on the first lap and his bike stopped after he tried to rejoin the race.
