ouch! Snapped fork, not designed for 170kmh huh? :O what was it a bloody Raleigh Activator.
I saw my mate do that on his BMX on a jump at coppul, what made it worse, apart from no helmet, they had laid plastic grid grid on the floor! that did its best to cheese grate his face. :O Also after snapping a BMX stem without trying I'm always paranoid about teh front end now, despite being quite a light rider.
