I ordered this to repair a factory xg750a clutch, and replace the judder disc with a full friction plate. The finish is great and it seems to bite harder than the factory clutch, although that may be because of the high tension springs that went in along with these discs. The only dimensional difference in these and the factory discs are that these come in at 3mm instead of 2.9mm. These are also an economical replacement, I purchased this entire set for less than the cost of two Harley friction discs.
