Race one winner Rea completed the podium after never quite being able to get on terms with the leaders, though the Castrol Honda man is another to have benefitted from a much appreciated large points' haul today.
Following the mechanical dramas of race one, Leon Camier bounced back for a strong fourth place finish, the Aprilia rider unlucky to lose time in the pack early on as he matched the leaders' pace in clear air. He also comes away a new race lap record of 1min 36.476secs.
Leon Haslam was rewarded with fifth after an afternoon spent busily defending from those behind, the BMW rider leading a close pack of Eugene Laverty, Michel Fabrizio, Haga, Jakub Smrz – who got a terrible start from second to end lap one in 15th – and Sylvain Guintoli.
Having shown promise during the opening race, Tom Sykes had to make do with just 14th and 11th place finishes, marginally ahead of Kawasaki team-mate Joan Lascorz.
Maxime Berger and Supersonic Ducati are off the mark after the Frenchman finished in 13th – his first finish of the year - ahead of Ruben Xaus and Ayrton Badovini.
Chris Vermeulen, meanwhile, did not start the second race having retired early in the first.
