The rules, or rule rather, is only this: no dirt bikes. Well, if you want to bring a dirt bike it has to have pure street tires or slicks. Last year someone raced a new Panigale, this year someone brought a $50k, fully restored XR750 Harley-Davidson flat track racer and took that out on the track (he blew out the clutch but luckily, had a back-up 1965 Indian in the truck). Last year, two guys rode down from Atlanta on Panheads with tractor tires. You never know what’s going to show up, but if it shows up, it’s gonna race.
