I read the reviews and some said that the seals fit loose but worked. They fit great for the forks on my gs700E. Very good quality. Great easy to read instructions w/ picture to go by. So far Im very happy with these seals.
I replaced my seals with stock ones from the dealer. They were difficult to install and leaked from day 1. I got new seals from Dennis Kirk. They were much easier to install. They don't leak, and they were half the price of the dealer. Delivery was very fast and D.K. kept close contact with me while the order was in process. They ever included a return label just in case there had been a problem.
I will be totally honest...these seals look super cheap and fit even worse... but THEY WORK. I have never had a single one leak on me. They dont fit into the carrier of the fork legs well at all...its almost like you could use two on each side but as I said, they work great. I have used these on my race bikes and have had no problems.
No leaks but these have A LOT of stiction, I think the design abandoned concern about how tight they grabbed the fork slider and just made sure they clamp it tight so it never leaks. Still a pretty low number of miles on them so this could get better, but not likely. The polyvinyl that these are made of wears very well but is not slippery. Will probably help if your sliders are very worn or pitted and regular seals tear and leak quickly.
