The rear of William Dunlop's bike made contact with the road several times at the same location where he was later involved in a fatal racing crash, an inquest has heard.
William, a 33-year-old father of two from Ballymoney, Co Antrim, was killed during the race in north county Dublin five years ago.
Another competitor, Paul Jordan, gave evidence that the Yamaha R1 superbike ridden by William had “bottomed out” at a dip in the road just before the fatal collision as well as the two previous laps while participating in a practice run for the Skerries 100 races on July 7, 2018.
