Honda rider Michael Dunlop got the better of road racing rival Guy Martin to win the Scarborough Gold Cup race for the first time on Sunday.
The Ballymoney man enjoyed an advantage of 11.5 seconds over the Suzuki ace, who was looking to win the event for the ninth time, by the end of six laps.
Michael also won one of the 250cc races and took three other podium finishes at the traditional end-of-season meeting.
Martin had taken wins in Saturday's Superbike and Supersport 600cc races.
The Lincolnshire rider won the opening 'big bike' race from compatriot Dean Harrison and Dunlop, with Harrison improving to win the second Superbike outing in which Dunlop finished third and Martin fifth.
The first 600 event saw Martin see off the challenge of runner-up William Dunlop and Fermanagh man Lee Johnston, who completed the podium positions.
Tyco TAS Suzuki rider Martin was forced to settle for second behind Martin in the second Supersport joust.
Michael came home ahead of brother William and the retiring Ian Lougher in 250cc race one, but Welshman Lougher took the flag from Michael in race two.
A number of the top challengers, John McGuinness, Harrison, Lougher, Bruce Anstey and William Dunlop, failed to finish the feature Gold Cup event, which was held in very wet conditions.
Chris Palmer and Ivan Lintin sealed two 125cc and Supertwins victories respectively, while Saintfield's Davy Morgan secured a double success in the Solo Non-Finalists races.
Ian and Carl Bell completed a sidecar treble.
