Flop test to check your head bearings.

First, jack up the front wheel off the ground  and hold the bars straight.

Now release the bars, if they drop to the side and bounce then the steering head bearings need to be tightened. 

Another test is once the front wheel if off the ground, grasp the front forks and try to move them by pushing and pulling, if you feel any movement your bearings are loose.


Loose steering head bearings can cause the bars to shake if you release them as you ride, it can also make you think your front tire is bad .

Check the steering head bearing before every riding season  to be safe.
