Greetings from a lurker who has benefited from the site already! Recently picked up a 1992 kdx 200 to get back into the sport and have been going through it getting ready for the summer. All has gone well but I've encountered a front disc mystery that has me feeling pretty dumb at this point. The front disc is worn down to the point of grinding into the bolts that hold it on and even with new pads isn't working well. Ordered a new disc online to replace the worn disc that's on there, only to discover it was the wrong one. I'm working with the vendor to send it back and in the meantime ordered an aftermarket 1992 kdx200 front disc from the local dealership which arrived today and is of the same incompatible configuration as the other one. In looking up replacement rotors, I see a lot of 4 bolt discs such as this:

These seem to be the disc listed for my bike on most sites.

The hub on my bike has a rotor fitting this image:

I'd rather not pay OEM prices and am looking for an aftermarket that will fit this hub, after searching in general and on kdxrider, I haven't found much in the way of information. It's possible a previous owner swapped for another wheel/hub or there is some variation in the front rotor for that model year. Maybe I'm going crazy or missing something, but apart from ordering from a questionable vendor in China, I don't see much available for replacements. If anyone recognizes that disc or can point out where I'm going wrong it would be much appreciated.

under no circumstances should bolts be digging into the rotor. even if the brake system is totally shot. Are you missing the spacer on the axle?

is it factory kawi forks still?

Post a picture of your setup so we can see what your seeing

Thanks a link to what the stock rotor looks like

Wow, thanks for the fast response both of you.
I think the previous owner/s allowed the pads to wear to the point of the caliper bracket engaging the rotor rather than the pad itself, only way to explain wear that close to the hub rather than where the pads engage. Here are two pictures, one from the side, one from head-on of the current situation:

I think youre missing a spacer. There shouldnt be any bare axle visible on either side of the hub, im pretty sure.

Take apart what you have and then look at the parts diagram.

The 4 bolt disks are for 93 and newer KDXs. 89-92 use a different hub, so try ordering a disk for a 90.

BTW, this one seems to be the right one....http://www.oemcycle.com/Item/product/900195823

Thank you everyone for the help.
EBC MD6036D looks to be the correct one, will follow up once it arrives so anyone else looking will have a reference.
As for the spacer, took the wheel off again to double check, what looks like axle in that picture is the collar and all parts accounted for.
