    The bike requirements per the regulations don't mention anything (that I can find) about requiring the rear axle nut to be secured with a cotter pin or the like. Can someone confirm that, although it is a good idea, it is not a requirement?

    Thanks,
    Steve

    It's not a requirement, but as you stated.....a very good idea. Why not just go ahead and do it. It shouldn't take more than 5 - 10 minutes at the most and you no longer have any worries about it.

    Change the cotter pin to a large diaper clip......it does the same thing, saves time and gives you piece of mind

    It's a new bike to me without the nut drilled. I'm out of town all next week to do something before my first weekend with this bike (2003 R1) on the track. It otherwise is safety wired and track prepped.

    Nut, Axle, or even better both.... One of my first times at Jennings someone had their rear nut come loose and just about guided him in the lake at 100+....

    A blob of silicon may be a good temporary solution if you're looking for a little more piece of mind.

    Do you guys drill the nut and axel or just the axel? Been waiting to do this just nit sure how.

    Seems like it would be hard to align the axel and nut up evertime if there both drilled? Unless the hole was pretty large

    If it's like my R6, the OEM nut is a locknut and it's not going to come off on its own anyway. No need to get carried away. I just drilled the axle for piece of mind. That way I can look down, and say "yep, it's not coming off". :)

    Thanks for the pic. Unfortunately mines a cbr gunna look for a castle nut and give that a shot seems like drilling on the threads would be a pita and it would walk all over or I'll screw up the threads.. rly not looking forward to this.

    It's not hard. Put on nut. Drill hole. Unscrew nut to clean everything up. It took me about 30 seconds. :)

    Using the castle nut will still require you to drill through the threads of the axle. Doing it as shown above is going to be the easiest and lowest investment way to do it.

    Ill give it a shot. Kinda thought castle would be better because it cant rly come lose. The pic above could back out a turn or 2
