Commentary from Steve Parrish and Keith Huewen
Superbike race one
Glenn Irwin went straight on at Juniper Chicane on his sighting lap. He'll be hoping he doesn't do that in the race.
Remember, if a rider has to jump through a chicane they have to stop and put their foot in the designated box, otherwise they'll face a time penalty.
The bikes are rolling onto the grid....
Superbike race one
Remember, this is a four-lap race compared to the six laps we are usually accustomed to with the big bikes.
This will be fast!
The riders aren't too far away from returning to the grid, and then it'll be the quick blast into Portstewart!
Superbike race one
Lee Johnston
Five-time winner at the NW200
You don't know what Michael [Dunlop] has changed or thought of since qualifying earlier. That's a brand new bike so it's definitely moving forward.
It's going to be a good one!
Superbike race one
Who do you fancy for this one then?
Glenn Irwin will be the favourite after his blistering pace earlier today (and he's looking to equal that Superbike wins record), but we know Davey Todd has been keeping him honest all week.
You can't discount Michael Dunlop, Dean Harrison or Peter Hickman from this either.
It could be rather tasty.
The Superbikes, led by Glenn Irwin, are away on their sighting lap.
Anyone else ridiculously excited for this one?

"I wanted to be part of the event, to come here and see it. It's a big bonus for me to get to do a lap as well.
"I've got so many home fans. They don't get the chance to come to watch me race, even in the UK. It's nice to come and show my appreciation but also enjoy the atmosphere.
"It's very seldom you get the chance to have a closed lap of the North West!"
Look who is in the (metaphorical) building!
Six-time World Superbike Champion Jonathan Rea will do a parade lap after the first Superbike race.
We wonder what Lee Johnston is thinking in the background.

There's just a parked car being helped on its way off the circuit by a flatbed truck around the start/finish, which hopefully won't cause too many delays.

BBC Sport at the North West 200
It's time for the shadow boxing to end and the real business of this year's North West 200 meeting to start.
The fact that the Superbikes have been added to the Thursday night race programme should go down well with the thousands of fans basking in the sunshine around the Triangle circuit.
Expect Peter Hickman's two-year-old lap record to come under major threat and of course Glenn Irwin sits one behind Michael Rutter and the late Joey Dunlop's all-time record of nine Superbike wins so there is history in the making too.
You can watch tonight's action live on BBC iPlayer and the BBC Sport website, with Lee Johnston joining Keith Huewen and Steve Parrish on commentary.
Stephen Watson is on the grid with Larry Carter, Jenny Tinmouth and Philip McCallen.
If radio your thing, you can join Michael McNamee and Orla Bannon, who are in studio with Jamie Hamilton and Maria Costello.
It's sunny and hot, which is something I can't believe I'm writing (given the North West 200's reputation for rain).
There's a cool breeze in the air, which keeps things in check.

In the gap between action on the track, many fans have taken the opportunity to explore the paddock.
Lots of mechanics and team members have been completing final preparations ahead of tonight's racing, and lots of fans heading for the ice-cream van to cool down in the heat!

It's race dayyyy!
The practice sessions are out of the way and it's time to get the all-important racing under way.
First up, we've a Superbike race to kick things off and Glenn Irwin will be hoping to equal the record for wins in the class with Joey Dunlop and Michael Rutter.
That's followed by Superport and Superstock races to round out the action for the evening.
You can watch it live on the BBC Sport NI website and BBC iPlayer, and you can listen on BBC Sounds. We've got you covered!

That's about all from us for now.
Practice and qualifying are complete and in a couple of hours' time it will be time for the first three races of the 2024 North West 200 international road race meeting.
First up will be the Superbikes over four laps, then the Supersports and finally the Superstocks, also four-lappers.
Roads close again at 16:45 BST and we'll be back with you in plenty of time to enjoy the video and text build-up to those races so be sure to join us then.
Bye for now.
Jeremy McWilliams speaking to BBC Sport NI:
"I think it'll be a good 'ding dong' all the way to the flag.
"Hopefully no one gets away and we are all together like old times, the old 650 class which was always the tightest race and I'm just glad that it's back to the way it was."
Peter Hickman speaking to BBC Sport NI:
"Everything is going really well, the little Swan R7 is going quite nice to be fair. It was a little bit of an educated guess to where we had to be at.
"It's the same bike I raced here last year and at the Isle of Man TT, but completely different engine and exhaust. We have done our own exhaust, which has been fantastic and sounds beautiful as well which is always good!
"It seems to be going pretty well, every bike I have come across so far I have been as strong as if not a little bit stronger, so that's a good place to be."

Practice has been completed for today as the roads must open at 15:00 BST so there will be no restart for the Supertwins.
Richard Cooper speaking to BBC Sport NI:
"Pete [Hickman] is very impressive for the size he is, to get the Yamaha R7 up there with some respectable times and he has surprised me.
"Hopefully we will have something for him come Saturday."
