you can lower any bike who have dog-bone type junction between pivot link and swing-arm
simply cut the dog-bone in middle and add 1/4 of inch of a steel flat bar who it`s the same
thinkness of the dog-bone and weld it ,whit tig or mig welder,you could reinforce the dog-bone
by adding small piece of steel flat bar each side of the dog-bone.this should be lower your
bike between 1 1/2 to 3 inch according to the swing-arm/shock ratio and don`t forget
to raise the front fork leg into the triple clamp as much as you could to balance the bike.
this is no expensive and you could still bought new dog-bone to put it stock again
longer is the dog bone lower is the seat,but don`t go more than a 1/2 of inch.
i did that on lot of kdx and kx and on several custom roadbike.
p.s dog-bone must be in steel may be to risky whit alu one
