4wd, full suspension, 70km/h

If that doesn't work, check out the pic here (link).

A little project for anyone's amusement. Instead of plonking some motors onto a standard mountainboard, a friend and I redesigned the board entirely over a couple of years, to incorporate full independent suspension and steering setups. 12KW of power, top speed between 70-80km/hr.  Called it BajaBoard, after the Baja1000 rally:)
