One potential cause is too little oil in the front fork; if this is the case, add oil to the fork until it reaches a sufficient level.

A bent front fork can also cause this issue, requiring you to change the front fork (it is recommended to contact an officially registered mechanic for this). Lastly, a badly adjusted rear shock absorber could be the culprit, so make sure to adjust it accordingly.
