We have always raced Busa's. Yeah the liter bikes are fast and can be made real fast but you show me a liter bike in stock condition with a dry shot of nitrous running 8.70's and I will be impressed. We have done so much to Busa's and the amount of go fast stuff that is available is insane. I will swear to it that the fastest bikes around are Busa's. You go to a Prostar race and all the fast stuff and all the grudge bikes are Busa's. We have several very fast Busa's that we have done.
