What is the rule of thumb for safety wiring the front axle and pinch bolts? On my 05 zx6r the axle and collar stuck out a bit on either side of the lower forks where you could drill a hole to safety wire. I am now trying to set up an 09 zx6r and both ends of the axle are recessed in the forks. A couple ppl have suggested drilling through the lower part of the fork and into the axle and collar but I really don't want to do this unless I absolutely have to. Just checking to see if this was necessary or if I could just safety wire the two pinch bolts together.. or if anyone had any other ideas.

Hope this makes sense, pictures would prob help!
