Anybody who's ever strapped themselves into a shifter-kart can attest to the fact that they are one of the most exhilarating rides available, and their capabilities are much higher than first expected. That being the case, when swapping the 125cc engine from the go kart with a 1300cc engine from a Suzuki Hayabusa, the resulting machine is nothing if not overpowered. A small blip of the throttle induces massive tire spin and power-slides are available at a moment's notice, possibly less. To handle the power-infusion, the frame was suitably strengthened and elongated with plenty of square-section tubing. We're not so sure that we'd have built this machine in the first place, but now that it's done, we really wish we could get a chance in the drivers seat. Follow along after the break for a video of the machine in action.
