Northern Ireland's Andrew Brady won the four-lap Junior Manx Grand Prix in wet and windy conditions on the Isle of Man's Mountain Course on Monday.
The race was marred by the death of 20-year-old Wayne Hamilton, who had won Saturday's Newcomers 'A' Race at the event.
Brady finished seven seconds ahead of Douglas rider Paul Smyth, with Stephen McKnight completing the podium places.
Meanwhile, TT star Ryan Farquhar won the day's opening 350cc race.
The Dungannon racer recorded an average speed of 97.787mph, to win his seventh MGP title.
Castletown's Chris Palmer finished second with Roy Richardson third.
Ballymena's Barry Davidson took the chequered flag in the 250cc race, which was run concurrently.
Peter Wakefield finished second with Maria Costello third.
Costello, who was the first woman to achieve a podium on the mountain course in 2005, was reported to have stopped at Governors Dip on her final lap and pushed her bike the 500 metres to the finish.
