You are both partially correct. If you have a cruiser style bike, they want a leather coat, above ankle boots, & full face helmet (no kill switch needed). If a crotch rocket style bike, they want full leathers/ kill switch, full face helmet, boots, etc., if faster than 10.99, slower bikes do not need a kill switch, but they would like all sport riders to have full leathers, if possible.
They realize that most sport bikes can have a kill switch, but most cruisers never will have a kill switch.
I ran a few times a few years back & had a good time. It really was different from launching on the street. Typically, on the street, the front end never comes up on my VTX, however it’ll pull the front end up about 6-8" with good traction at the track.
It is best to go on a cool day or evening, so you don’t overheat from the leather(s)/full face. I’d like to run my bike sometime soon, as I have made some mods & don’t know how much better it really runs. I mainly rely on my butt dyno.
