I still don't think the Boss Hoss would make a good drag racer, though. Too much mass to get moving and too little tire to put the power down through.
Maybe roll ons.
Really they launch very well. Yes they do spin the tire more than pretty much any other vehicle in the Universe(yes I being facetious). The older clutch driven models had more of a problem with traction than the newer automatic models(which also happen to have a reverse which is a godsend). The automatic models with the torque with the two speed auto are really very quick. Their topend is limited to about 150though so at the very top the rice bikes will end up beating them, it will just take them a while to catch up to do it. The newer models are coming with Avon 230 venoms on them which is a good grippy tire as opposed to the old Goodyear eagle tire which if not on a car pretty much sucks.
