Davey Todd emerged the winner in a close battle with Joe Talbot to boost his championship points lead at Donington Park.
From pole, Todd was first into Turn One but Talbot was right behind him, hitting the front moments later and leading for a handful of laps until Todd found a way back ahead.
From there, Talbot kept him honest, sticking close to his back wheel but despite putting up a strong fight, was unable to topple Todd and had to settle for second.
Scott Swann took third, ahead of Tom Ward as David Allingham rounded out the top five.
