Nice Bike!! Are you going to be running a series like AMA Dragbike or Mirock? As for leathers, you can check with Vanson or Bates, they are both popular with the AMA Dragbike series racers.
I have witnessed 2 Top Fuel bike pilots come off their bikes at the top end at over 200mph, and they both only suffered minor injuries and very little road rash wearing Vanson leathers. Bottom line....get good leathers.
I've seen some crazy fast passes on no bar bikes. Of all of the different classes, Pro Street has to be the most insane class. The fastest I've personally seen ran a 7.202 at 204.66 and lost on a hole shot.
