As the riders, apart from Leon Haslam who decided to sit the race out, lined up on the grid, Tom Sykes was missing. He had crashed on the sighting lap, but he got his Kawasaki towed back to the pits with ten minutes for his team to rebuild the front cowl. If his bike were put back in the garage, that would be his race over, so his team brought their tools and mechanics out to the pit lane to frantically try to get his bike ready. As it was, he had to start from the pit lane, hoping that the small grid would allow him to score a couple of points.
Eugene Laverty, whose second place was now the frontmost grid position, led into turn one and set about trying to shake off his shadow, Jonathan Rea. As Laverty and Rea built up a gap from Marco Melandri and Sylvain Guintoli, Tom Sykes returned to the pits to let his mechanics have another go.
Laverty and Rea continued their pairing as Laverty pushed down the straight and Rea closed up through the lap, while Sykes had to pull in yet again, eventually returning to the track seven laps down. Marco Melandri was caught and passed by Sylvain Guintoli a third of the way through the race and this would be the start of Melandri's woes as his tyre then started to degrade and he became the grid's whipping boy, holding his own down the straights, but being passed by a different rider almost every lap. Melandri would eventually finish in 12th place.
Eugene Laverty would manage his lead, dropping Jonathan Rea, eventually holding over four seconds to the flag, winning the race, while Sylvain Guintoli caught and blasted past Rea on the straight for second place. Rea continued his run of podiums at Portimão weekends, but he was visibly frustrated with his bike.
Loris Baz, some ten seconds behind, got fourth place ahead of Chaz Davies and Carlos Checa, while Tom Sykes, some seven laps down, set the lap record, scything through the field for no points. Laverty's win puts him in third place in the championship, only eleven points behind Sykes whose misfortune served to extend Guintoli's lead to 28 points.
BMW were scrutinising the tyre on Davies's bike and comparing it to the obvious duffer that shod Melandri's S1000 RR.
