I've often wondered what that lug was for because mine is supposed to be an '02 bike as all Foggys are; so has no speedo drive on the front wheel, but as I have been finding some '01 bits have crept in as they were not built on the main assembly line but in another room and using whatever they had by the looks of things, like the '01 ECU that they mated up with the '02 loom on all of them which kinda works 99% with some 1% weirdness thrown into the mix!

But having googled for pictures it looks like most of the Foggys that I can see clearly that side did get the mudguard without the lug so I'm guessing mine has an earlier '01 replacement one. Don't know if there is a captive nut in fixed there or if it's just a hole though?

It was that ebay picture of the S4 for sale with like 1000 miles that did it. But glad to be of help and another mystery solved.
