I looked at my SV rear axle more closely, it isn't a plain nut but neither is it a Fuji nut. I bought the bike new in 2016 and have had the axle out a few times with no issues. I haven't read about anyone having issues here or on the US forum, whereas you can find people with the issue on the XSR and MT-07/FZ-07 forums.
