Cooper gets a mega exit out of Mill Road and manages to build a bit of a gap.

Harrison is all over Todd for second now, and the pair are right on the back of the #47 again as the slipstream comes into effect.

Todd is right on Cooper's back wheel into York. He's not letting him get him get away and Dean Harrison wants a say in this too!

Richard Cooper has made a bit of a break there.

Cooper just suits that bike. It is the bike he has ridden before on many occasions.

It's Richard Cooper by 0.178 seconds from Todd and Harrison.

There's a small gap and then Hickman, Dunlop and Coward are in another tight battle behind.

Seeley is seventh, but almost four seconds off the lead.

Cooper tries to pull the pin on the run to Portrush but he can't escape Todd and Harrison.

Peter Hickman, Michael Dunlop and Adam McLean are in the mix too!

This is a huge scrap already! Richard Cooper leads from Todd and Harrison - and a huge number of riders behind!

Slightly more orthodox entry into the corner that time around from Davey Todd compared to the Superbikes!

It's like a swarm of 190mph bees on the run to University - what a sight!

They are three wide at the front and Todd and Cooper almost come to blows at the tight left hander!

Davey Todd gets the jump off the line and leads into York!

It's the 600's first visit to slipstream city. This could be wild!

A look to the lights, the engine notes rise....AND WE ARE RACING!

That Ducati [of Michael Dunlop's] has a unique and a superb sound to it.

First Minister of Northern Ireland Michelle O'Neill speaking on BBC iPlayer: "It is my first time here so I am absolutely delighted to be here and everyone is absolutely buzzing.

"Every day is a school day so I am getting a lesson here on just how it all works.

"The crowds that it brings, 100,000 will be here possibly on Saturday, and with the weather it makes it even better."

The bikes are rolling back onto the grid and it won't be too long before we are off and running in this one.

Davey Todd's win in the Superbike class is the first by an English rider - and indeeed any rider from outside Northern Ireland - since John McGuinness took victory in the premier class in 2012.

Making up that NI dominance is 11 wins for Glenn Irwin, four for Alastair Seeley, two for Michael Dunlop and one from the late and much missed William Dunlop.

I'm going for Richard Cooper for this one.

We have seen in Supersport races gone by that if you are in the top six or eight in the last lap, you are definitely in with a chance of winning the race.

Yamaha's Adam McLean speaking on BBC iPlayer: "We'll give it a go.

"The times in the 600 class this year were really close so it is a really good depth of field this year.

"I am happy to be there abouts and if we can get a good start, we'll see how we go."

The riders are off on their sighting lap ahead of the Supersport race.

Yamaha's Richard Cooper speaking on BBC iPlayer: "I feel ready. We have had a good practice on the Supersport bike. A lot of laps on my own and the pace has been there.

"It was pretty tight between me and Dean Harrison and with a tenth of a second between us, eight miles is going to prove to be a tough race!

"Supersport is always tough and you never know where the challenges are going to come from."
