    Cooper nails the final corner this time and leads at the halfway point.

    McLean had a look into Juniper but couldn't pull it off.

    Hickman is into the pits with an issue, so the wily old Jeremy McWilliams is third!

    That Richard Cooper mistake has certainly given us a race!

    Juniper Chicane is a favourite passing place. I think out of all of the passing places on the track, that is the one that everyone practices for in the last lap.

    Lap 2/4

    It looks on the replay as if Cooper got in too hot, maybe caught out by the crosswind.

    The grass is bone dry so he didn't drop too much time, but that's definitely not the ideal racing line.

    Cooper across the grass at the final corner! Adam McLean is into the lead!

    That was a huge moment as Cooper ran wide into the final left hander and skipped across the grass.

    Hickman is third and McWilliams fourth.

    Can Cooper regroup?

    Adam McLean has closed the gap to Richard Cooper a little bit and they have a bit of a gap between them and Peter Hickman [in third].

    The front four have broken away from the rest of the grid.

    McLean is still right with Cooper at Mather's, with Hickman and McWilliams just behind.

    There's five riders bunched right together as they power into Coleraine.

    McLean is right there and Hickman, McWilliams and Jordan are in the mix too.

    It's Richard Cooper who gets the jump off the line and leads the way on the run to Portstewart!

    Richard Cooper is definitely going to be hard to beat, but I wouldn't put all my money on him.

    Peter Hickman, they have worked hard on that Yamaha and that is the bike that won last year and they have done more alterations on it.

  20. 'We have improved the bike quite a lot'published at 10:12 British Summer Time 10 May

    Peter Hickman, who starts in fourth, speaking BBC iPlayer: "There are a lot of changes on this bike, we have improved it quite a lot.

    "I am sure everyone else has improved their bikes as well so the proof is in the pudding and we're about to find out.

    "The wind has changed quite a lot since Thursday so gearing is going to play a big part and I'm not entirely sure what I am going to do yet, but I'll do the opening lap and make the decision."
