4 wheeled motorcycle?

Sounds cool.

When you watch the video of the 4MC being ridden around corners, you realise that this bike seems just about uncrashable. At full tilt, its wheels actually move slightly further apart, increasing stability. That, along with the added manoeuvrability that its tilting wheels provide, make the 4MC a demon in fast corners. And at very low speeds, there’s a hydraulic anti-tilt system there, which ‘locks’ the wheels and allows the machine to be ridden very slowly, without the rider having to put his feet down.
