ZXR 750 front axle nut size?

Hi guys,

Just after a quick answer on this. What size Allen keys do I need to remove the front axle on a 1993 ZXR 750? Google and search have not been my friends this morning.

Cheers in advance,

Tom.

Leave one side small clampy allen head bolts done up and then undo the other side, then you only need one of the big hex keys. I had one made out of a bolt and a couple of nuts by the local bolt place, can measure them tonight if no one replies beforehand.

20something mm across the flats from memory.

I have a heap of these obtained from owning 5 different ZX somthings and guess what.....the ZRX is another size yet again. I'm gonna buy one of those multi size jobbies
