the only thing up front is the driveshaft/coupling, axles and the diff. My first thought would be the driveshaft coupling, but you said it seems to be pulling fine. What year is you bike? its possible the 4wheel drive tried to dissengauge if it has 2-4 select on it.

Just play it ear and see what happens it might have been a freak accident, it may never do it again. it's also hard to pin point a problem if you cant find it. If there is or was a problem I would think it will show itself right away.
