I have a set of forks off of a '99 Supersport in good condition. They have 10,200 bikes on them so they are not due for service yet. Seals are good with no leaks and the stanchions are perfect. 50/54 clamp diameters. There are a few small blems on it.
These are the non-adjustable models with 65mm caliper mounts, should fit a ton of bikes.
