  If your Baotian Scooter is inclining to the roadside, it could be due to several factors. The steering stem rotation might not be easy, in which case you should refer to “Front Fork Service”. A bent shock absorber could also be the cause, and you should refer to “Front Shock Absorber Service”. Other potential issues include shock absorber oil leakage, a bent front axle, incorrect wheel mounting (refer to “Front Wheel Service”), roundness error or deformation of the wheel rim, or inadequate tire pressure.
