now thats what i figured out concerning the rear susp stiffness. obviously, the dog bones to swinger mount is too low on the gixer swinger compared to the b12 swinger, thats why progression doesnt work
wrong way
right way
a medicine is
1. to use a higher profile rocker
2. to use a longer shock
btw, the susp starts working when the bikes lowered, coz the angles'd change and become 'workable'
