Just did mine and used the Acerbis SuperMoto fender - it bolts straight on without any cutting or modification.
I also bought a set of generic KTM SX85 style fork protectors.
It all fitted really well and the job was down in about an hour.
I routed the ABS cable up the front of the protector as I didn't like the original routing around the side of the axle mount. I reckon where it was running originally, it'd get snagged on something if the bike went down on the left side!
These fork protectors have a join at the rear so it was easy to route the brake lines inside the protector and cable tie them to the fork leg
Nice clean look and cable routing
