If the bolts are the allen/hex/torx kind with a dot in the middle, just put a small flat head in there and remove that dot, or go buy some security bits.

If it's any other kind of bolt, use a file and cut a flat groove into the bolt, then either use a chisel and light taps with a hammer, or use a flat head screwdriver to unscrew it.

This is a very common problem for the yamaha xt 125. I suggest that you either buy a new Heads up display or you take it down to yamaha and get them to fit another one, which i think might be free of charge due to it being a problem with the bikes.
