OK, here is the deal, those are fork seals only. I think what you are referring to is the DUST boots. Those are NLA from Suzuki. But there is a member of this board in France who makes wonderful reproduction boots, look just like OEM, but made of better material.
Hi I have used these seals on my GT500 and RG500 no problems at all, the GT has a small amount of pitting and no leaks the dust covers from françois. Are excellent
