how about this nitemare
its a 92 honda st50 or 'dax' as they are also known. we binned the 50cc engine and stuck a race tuned 5 speed 100cc two stroke in it with a race expansion pipe(altough in the pic it has a standard engine/un tuned exhaust in it) we widened the rear swing arm to get the widest scooter tyre we could find on the back (140!) and lowered/uprated the suspension.
basically it was unridable. the thing would lift its front wheel in first second and third just off the throttle. the guy that tuned the engine (some mad aussie) claimed that it should have about 30hp and i rekon he was right!
its for sale by the way, would make a great pit bike!!
