Never crashed because of it, but the only bike I've ever ridden that actually scared me was a victim of excessive torsional flex. Going downhill at speed, the rear end would flex so much every time I hit a bump that the bike would literally change directions. Not a comfortable sensation, especially at 40+ mph... This was a titanium frame from a very well regarded name (E___ M_____ Ti AX, built by L_______). Soured me on Ti frames for good.

ps - no, it wasn't wheel flex: my light steel bike w/the same wheels has no such problems. Nor was it fork flex, since I was running a Columbus Max steel fork, and the problem occurred only when the rear wheel hit a bump.
