Just got back from 310+ miles of hard-core riding and I can definitely report that the Motivation bar ends are worth the money. They don't eliminate all the vibration, but I noticed other riders having to slow to shake their wrists and not me.
The AP rearsets also quelled peg vibration.
Now if we can get a solution to the throttle tension...
My Sharkskin full belly needs to be dremeled as it hit the sidestand & broke.
Wish I had known before having it painted.
