Raceway Park in Indy,
I've seen people with textile, Not sure of there times? Guy was on a 600.
Leather gloves, jacket and High top boots. Require leather pants if you go over 120mph.
And also require NHRA license if your in the 9's.
They haven't checked the rating of my helmet.
And I haven't put the tether on my bike yet.
This all from Test and Tune nights.
They probably inforce the rules more at a race.
