These seals are the best for the money, they really are made of good quality materials and rate up there with the OEM seals. I have been using All Balls products for the last 20years and have yet to seen anything fail prematurely.
If you are looking for a complete kit as advertised, you will not get what you need. The fork seals are fine and seem to be of good quality, but the dust seals will not fit the KZ1300 and are useless.
2 The seals look different than traditional seals, but the manufacture warranty's them from ever leaking . Time will tell and I can't provide any feedback since with just install them. My only complaint is that the dust seal is not a snug fits on my fork and kept coming loose so I had to use some tape on the inside to take up some space and make them fit snugly
