Seen this a long time ago, always worth seeing again…
too bad this ones not somewhat loca, and too bad at 137mph avoiding Buffalo pothotles would be impossible- but then again this is for track use only right 
some of those karts have really small engines on em but are really fast too. i had an idea to pick up a sport bike motor and build a kart that was a little bit bigger then the ones showed. building of getting a frame really wouldnt be the hard or expensive part. Well building might take some time and effort and be hard but u can find frames anywhere. The expensive part is the braking system. You can find sportbike motors with the full harness on ebay for a couple hundred. You attach the clutch handle to the steering wheel, convert gear shifter to a handle on the side, brake and gas pedals. Throw a live axel on the back with a sprocket to fit the bike chain, mount the motor on there and uve got some serious power on a kart that is in all likelyhood gonna be faster then any car.
I want to fab one. Whos in.
i was planning one last year with a snomobile engine with hotrodkid, and i am always interested in doing this
Well, now that I think about it, Im not going to be around for long… I run off at the end of May, and wont be back for a few years… I WILL have one of these down the road though.
