I have measured the holes in the bottom yoke of the triple clamp. The hole centres match the same as a WR/YZF moto-x/enduro bike.
So I reckon that a pre-drilled mudguard from the like of UFO or Acerbis will fit.
The only short fall will be the back part of the mudguard will be hitting the radiator grill. I think I will cut the read of the mudguard away......
