Product Description
300 SX steering stabilizer choices for KTM 300 SX riders (2023): a complete kit, a mount kit only, a frame bracket and a bar clamp. Every option below comes from Scott's own fitment list for this bike. When the 300 SX's front wheel hits something and the bars try to snap sideways, the damper resists that fast movement. For these years the sub mount complete kit is part DS-SUB-6125-01 (about 2.7 lb), the sub mount complete kit is part DS-SUB-6125-01R (about 4.5 lb) and the sub mount mount kit only is part DM-SUB-6125-01 (about 1.9 lb); 5 more options are listed below.

What does a 300 SX steering stabilizer do?

What is a tank slapper, and do I need a steering stabilizer on my KTM 300 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 300 SX?

How do I set the damping on a 300 SX steering stabilizer?
