I managed to get side covers off ebay but the one is slightly more faded than the other, you've got to look at them at the same time to notice, which is impossible. I wouldn't use them in anger though, too rare, so I've got old mended ones for that. My other bike sports A5 side covers. I also got a headlight complete, after patiently buying all the bits bar the surround........ Don't just look for the headlight under KLX, 3 KDX models used the same part. I've used that trick on various different makes and got stuff cheap as a consequence.
Thing is KLXs may be rare but so are the blokes that want them. There's quite a bit of stuff on ebay for silly prices and no one buying.
