that is this one thing that a guy made. the bike is a 01' 929, the front wheel rest on a trampoline, and the back is on old dyno machine. Anyway it is pretty much a wheelie training machine type deal. you can't loop it theres a rope tied to the front wheel, and you have to use the same amount of throttle/clutch combination, to get it to come up, not enough it dosn't come up, and two much and it just spins the dyno drum. It is sapposedly the closest thing that comes to actually doing a wheelie on the road, and if you screw up, there is no road to get rash from.
