The error would allow Davies and Salom to gap the Frenchman, the latter duly taking advantage of the clear air to pounce on his rival for the lead of the race at Stowe. However, Salom would go in too hot and run wide, allowing Davies to retake the position.
It would prove the final significant act of the race, Salom shadowing Davies but unable to do anything to prevent the Welshman from completing another victory, arguably the finest of what is turning out to be a superb season.
With four races remaining and a maximum of 100 points available, Davies's victory sees him extend his lead to 42 points over Salom now, while Foret holds third even though neither has won a race this season.
Indeed, Foret was able to hold onto third, but only after resisting pressure from a remarkable Rea, who hauled his Step Racing bike into podium contention from several seconds adrift to challenge his Honda counterpart on the final lap.
However, after a series of heart-stopping moments as his bike – almost completely devoid of grip – bucked and weaved over the bumps, Rea's luck would run out on the very final corner as he slid off. Though he'd get going to console himself with 11th, it was scant reward for a brave performance.
His misfortune would see Roberto Tamburini come through for a fine fourth place finish, while Massimo Roccoli had the satisfaction of beating factory Kawasaki rider Broc Parkes to fifth position.
Behind them, Balazs Nemeth put in an excellent performance on the unheralded Team Toth Hungary for seventh – by far his and the team's best-ever WSS result -, beating out Honda trio Miguel Praia, Marino and James Ellison.
Behind Rea, former championship leader Luca Scassa's season goes from bad-to-worse as he lumbered to 12th place, while Alexander Lundh, Ronan Quarmby and Vittorio Iannuzzo made up the remainder of the points' finishers.
