Tom Sykes completed a perfect day for the factory Kawasaki team after battling to victory in race three at Brands Hatch.
Sykes picked up where he left off in the second encounter as he rebuffed Ryuichi Kiyonari's best efforts for much of the race, the World Superbike racer proving too strong for the former BSB champion.
Starting in third position on the grid, behind pole sitter Michael Laverty and Kiyonari, it was the Japanese rider that snatched the lead from the Suzuki man into Druids, with Sykes promptly following through just a lap later.
Kiyonari pulled into an early advantage but despite his best attempt to gap Sykes, he was unable to break the tow as they entered the home straight and into lap five, the Kawasaki bucking and sliding as it slipstreamed into the lead.
Kiyonari gave chase over the remaining 15 laps, but while he was often quicker than his rival heading out of Surtees and into Pilgrim's Drop, the straight-line speed of the ZX-10R would keep the CBR1000RR at arm's length.
While it was a second win of the day for the Paul Bird-helmed Kawasaki team, Kiyonari still had reason to celebrate after he moved to the head of the BSB standings for the first time this season. He also has the largest number of podium credits, ahead of Tommy Hill and Josh Brookes.
A third podium of the weekend has also seen Michael Rutter lift himself just off the series leaders as he completed the inevitable by guaranteeing himself a title showdown slot.
He had been contesting the final podium slot with Michael Laverty, but the Relentless Suzuki rider suffered only his second retirement of the season with a fall at Druids on lap 14. A terrible afternoon for the TAS team, race one winner Alastair Seeley fell for the second time today on exactly the same lap at Paddock Hill Bend.
A strong end to an otherwise difficult weekend saw Tommy Hill finish the third race in fourth position, ahead of James Ellison and Josh Brookes, the Swan Honda rider wrestling back fifth off the Australian on the final lap.
Yukio Kagayama and Stuart Easton crossed the line seventh and eighth, ahead of John Laverty, who kept himself in contention for a title showdown spot in ninth position.
Simon Andrews rounded out the top ten for MSS Colchester Kawasaki team, ahead of Ian Lowry, Tommy Bridewell, Chris Walker, Peter Hickman and Tom Tunstall.
In the Evo class, Pauli Pekkanen recorded his first victory of the season after title contenders Hudson Kennaugh and Steve Brogan both retired with mechanical difficulties.
