England's Steve Plater won the blue-riband Senior TT on his HM Plant Honda in the Isle of Man on Friday.
Plater was 20 seconds ahead of McAdoo Kawasaki rider Conor Cummins, followed by Gary Johnson and Adrian Archibald.
John McGuinness, who led for the first three laps, upped the lap record to 131.58mph but he retired with a broken chain at Cruickshanks on lap four.
Plater and Cummins also smashed the 130mph lap barrier and Guy Martin retired on lap four while in third.
Bruce Anstey, Ryan Farquhar and Michael Dunlop also retired while Ian Hutchinson and William Dunlop came off without injury at Quarter Bridge.
Plater also won the inaugural TT Championship Series, collecting the Joey Dunlop Memorial Trophy and an additional £10,000.
It is a second TT success for the Lincolnshire rider after winning in the Supersport class last year.
McGuinness led Plater by 3.5 seconds after lap one, setting a new course best of 130.95 in the process.
Plater also opened with a fast lap at 130.49 but McGuinness extended his lead to 16 seconds with another record lap on his second circuit.
The Morecambe man enjoyed an increased advantage of 18 seconds following his third lap, before a broken chain ended his hopes of a fifth consecutive Senior success.
Cummins set his fastest speed of 130.22 on lap three.
