Dunno if anyone has ever tried to ride a real short-track speedway bike, but they are pure evil with a capital E.
500cc single cylinder 4 stroke, with crazy high compression ratio, burning alcohol and direct drive (no transmission). They weigh about 170 pounds wet.
The ultimate in torque.
I tried riding a jawa once at saddleback mountain on the old TT track.
Flipped it once which was not hard to do. Incredible torque and instant throttle response and gearing from hell.
I got it going in a straight line easy enough but could not control the slide at all.
Finally learned the trick, a bike like that must be ridden in anger. You gotta be hard on the throttle to keep the tire spinning to maintain the slide.
I eventually got it to slide a little but was never smooth.
Did I mention they can do 80 mph in a slide and have no brakes?
It looked kinda like this one:
