I wonder if it's faster than a hayabusa. That's badass. That's a good reason to learn how to weld . Mine would have a 5 point harness and a cage, though. And i'd be looking into one of those turbo kits.
Sleeper - the cage and harnesses are a waste of time - think "motorcycle" when it comes to Karts. You don't want to be on that thing if it gets out of hand.
that machine is a lot of custom fabrication. I have a 125cc shifter kart for sale if you guys want what they started with before the motorcycle engine was strapped on there.
Are you serious? I had a slow one for a while in the early 90's, it would only top out at about 80mph. It had an alcohol burning Briggs & Stratton 5hp. They're easy to find. You can be on the track for $1,000-$1,500, just no telling what your hospital bill will be.
