What is a tank slapper, and do I need a steering stabilizer on my KTM 125 SX?
A tank slapper is a fast side to side shake of the handlebars. Our guides explain what causes it and how to decide whether you need a stabilizer: tank slappers, speed wobble and head shake and do you need a steering stabilizer.
Will a Scott's steering stabilizer fit my KTM 125 SX?
Fit depends on the model year. This page covers 1998-1999 of the KTM 125 SX. Choose your year in the fitment bar and match the part number on the kit to your bike. Part numbers are explained in the kit guide.
How do I set the damping on a 125 SX steering stabilizer?
Scott's says its off-road units damp as the bars turn away from center and let them return freely. Scott's also says the damping is adjustable, including while riding. The install guide covers settings.
How do I service a Scott's 125 SX steering stabilizer?
Scott's says to treat it like suspension, with an occasional oil change depending on how hard you ride. See the service guide.
