I think it is a 5/8 and yes you have to grind the heck out of it.

I bought a 16mm deep socket for $8 and ground it down. Fits perfect!

Has anyone else ground a socket down to do this ? the ktm specific socket is really weak as its so thin, I have cracked two of them now trying to undo my sparkplug on my 09 250sxf. Previous owner seems to have cranked on it pretty well.........

You need a thin-wall, 16mm, six point, deep socket. The proper ones are 19.9 mm in diameter.

Or you can buy a six point, 16mm deep socket at Home Depot for $4, and use a grinder to reduce it from about 22 mm to a hair under 20.
