Bolstered by tales of the great Joey Dunlop, it attracts hundreds of European racing fans to Northern Ireland every year.
Joe and Sue Pilmore and Charlie Karen Tomlinson came from Derbyshire early in the morning to secure hotel rooms.
“This is the first time we've come to see the North West,” said Joe.
“We normally follow the TT racing like the Isle of Man races, but we were enticed by the prospect of road racing.”
Charlie added: “We think that road racing is much better to watch than TT racing. It's the excitement and the ‘do or die' attitude that the riders have here.
“There's an added danger compared to racing Moto GP. If you come off here you're in trouble.”
In a male-dominated sport, one Italian woman is determined to make a name for herself.
Simona Zaccardi was making the final adjustments to her machine before heading out for another few practice laps.
“This is my first time at the North West 200,” said Simona.
“It's just incredible here. I have some fun with the other riders because I'm a woman and I joke about with the other guys.
“I am small and my bike is heavy, so it can be hard to handle sometimes.
“When I am on the straight the other riders take over me, but because my bike is smaller I can get them back on the corners. I love racing, but it makes it even more pleasurable for me when I beat the men.”
David and Elain McNairn and current Scottish road racing champion Bruce Burney have come over to support their friend Donald McFadyen, who is competing tomorrow.
David said: “This is my fourth year here and Elaine's first. There's a huge Scottish contingent over here for the weekend.”
Bruce added: “It's different from other types of racing because of the great sense of speed you get from it. It shouldn't be allowed, really. You've got all of the elements to compete with — the wind, the big straights and the chicanes.”
Gary and Randy Van Marsdyke, Gary Von Drummel and Franz Fleuren have flown in from the Netherlands for the weekend.
“The North West is different. It's like nothing we've seen before,” laughed Franz. “It's racing in its best form — back to basics.”
