I have a used set of 126MM LTR Lowering Links for sale. Took these off my bike when I had my suspension lowered professionally. Asking $75. Thanks for Looking.

Not many of us have the 4 strokes. I seem to recall that the motor has some commonality to the suzuki motor. Maybe try and cross reference some microfiche. I may be way off too but thought I would throw it out there.
