Lincolnshire’s Guy Martin has sealed his 10th Ulster Grand Prix victory with a brilliant triumph in the blue riband Superbike race at Dundrod.
Martin took the lead on his factory Tyco Suzuki from Honda TT Legends rider Michael Dunlop on the opening lap and stayed in front until the chequered flag.
It was his second victory of the day after the 31-year-old earlier won the opening Supersport race from Bruce Anstey.
Martin also won the feature Superbike race at Dundrod in 2012.
He set a searing pace and opened a lead over Dunlop, who gradually began to reel in the Suzuki rider.
The pair were inseparable on the seventh and final lap as they encountered slower riders, but try as he might Ballymoney man Dunlop was unable to find a way through as Martin held his nerve.
At the finishing line Martin’s margin of victory was 0.038s over Dunlop, whose older brother William took third place on the Milwaukee Yamaha YZF-R1.
Padgett’s HM Plant Honda rider Anstey finished fourth ahead of Gary Johnson on the Lincs Lifting Honda with Dean Harrison edging Lee Johnston (East Coast Honda) for sixth at the finish.
Conor Cummins had been running with Anstey and Johnson until he slowed at the end, eventually finishing tenth on the second Milwaukee Yamaha.
