This is how the rim lock works on your dirt bike.
In case you were wondering what that bolt sticking out of your rim is for, that’s the rim lock.
Your rim lock is simply a clamp that holds your tire in place on the rim and can be found on every dirt bike.
Your rim lock is designed to fit between the tire and the tube, with metal cleats on the bottom to grip the inside of the tire bead.
When your rim lock is in good shape and seated correctly on the rim, your tire WILL NOT MOVE.
