normally found marked on the disc and can relate to several things like original disc thickness, disk material and also how far across the pads can come in the callipers

As Skidlids has said - there will be a wear limit stamped on the inner edge of the disc - most Ducs I've seen on standard discs are 4 or 4.5mm min thickness depending on them being 4.5 or 5mm thick when new as a guide.

One of my sets of discs has a wear limit of 3.6mm. As you are quite away below this with one disc I would look at replacing them. There are Pairs of New Wavey discs going on Ebay for £149. My mate with the Powervalve engine in the Mito has just ordered some so waiting for his feedback on them.

Don't run around with overly worn discs. This happened braking for turn 15 @ Sepang on a track-day. The cast iron disc broke up and tore the caliper off the fork leg. Luckily there is lots of run off there.
