Steering handlebar stops?

[Dead Eye]

Slight misunderstanding of "twisting" - its not an individual fork that is twisted on its own axis.

Basically, the top and bottom yokes can become out of alignment. Think about it as both fork legs are secured in the bottom yoke but the tops aren't. If you were to sit on the bike and pull one of the tops of the forks towards you, it would force the other one away from you - but the bottom yoke would still be exactly where it was before. End result is "twisted" forks and this can be caused by a crash / off
