(Got-Busa? @ Oct. 17 2006,07:06) Depends how lax the track is on rules.
You need LEATHER jacket, gloves, boots and pants (if you trap higher than 125mph) but some tracks don't inforce the pants. You also need a tether cord that attaches to your body in case you leave the bike.
Not to mention if you don't have the license anything faster than a 9.99 will get you kicked also. Again it depends what the track is allowed since I've made many 9-second passes without a license to do so....
Those are NHRA but IHRA should be pretty similar for bikes.
Good luck!
