I have never participated in a track day- but always read the announcements.
From a MAX BMW Limerock track day announcement-
Requirements for you and your bike:
IF YOU DO NOT MEET THESE REQUIREMENTS, YOU WILL NOT BE ALLOWED TO PARTICIPATE.
Suit - You need a full-coverage protective riding suit. The suit can be a one-piece suit or two-pieces that zip together.
Feet – You must have boots that cover your ankles
Hands – Look for hard material on the knuckles and fingers to protect you in falls where your hand grinds against the pavement. Choose gloves with a generous gauntlet and a strap that encircles the wrist
Head – Properly fitted helmet
Insurance- Each rider must present a valid medical insurance card
All motorcycles must pass a technical inspection before riding. If your bike fails technical inspection you cannot ride it on the track until the failure is corrected. Please make sure that your bike will pass a technical inspection before arriving at the track.
Mufflers required > 88dBA
50% tire tread remaining
50% brake pads remaining
The throttle must operate smoothly with no binding or sticking. Open the throttle 100% and release it. The grip must return fully to the original position without sticking.
Properly adjusted chain
No fluid leaks (safety wire and coolant drain are NOT required)]
I have never read an invitation to participate in a track day that didn’t have an insurance card requirement.
