If you don't have these you are Missing Out. These Dog-Bones are a Must have. I Just put a set on and reajusted the rear end And Man these little things Rock. You know the KDX is a Bad Wheel Hopper on Down Hills and Hard Braking the rear end Just Chatter's Like Krazy, Now No more Chatter Just smooth Braking, Also it change the ratio on the linkage for the better IMO, It handles Roots and Ruts better and is more Stable at Higher speeds. Nows Here's the part I like the Best, In a 2-hour Race Harescramble when you need to sit Down NO More Sore Tail after the race or the next day at work, Made racing more enjoyable, Made 4 laps on a 8.3 mile course, They Will Inprove your Riding Level and Skill, They Help Me, Just wanted to share this Infor Ride report for You KDX-ERS.
