V100s rear wheel socket

Help needed here. I want to purchase a rear wheel nut socket. But i can’t find one online.
The moto guzzi manual i downloaded for my V100s says the socket size is a M60.
Online forum quotes are all showing different sizes for this socket.
Do Moto Guzzi sell a socket, and if not, can someone direct me to where i can buy one

visually the nut on the Stelvio looks so similar to the Ducati and Speed Triple ones, i would take some measuring calipers and go to my local Ducati/Triumph shop

I bought a 65mm socket online that fits my v100 Stelvio perfectly, a Mandello may be different. It’s a three quarter inch drive so I also bought a half inch converter to fit my torque wrench. I’ll see if I can get a photo of it tomorrow so you can shop with a picture. The socket and adaptor just fit in the storage space under my seat.

It’s 65mm. Apparently, the same size as Ford Transit hub nuts. Yes, they all seem to be 3/4" drive, but are all over eBay etc. I got an impact rated one because the torque is supposed to be about 250 Nm. Undoing that is going to need even more, so I’m sure it’d really need a rattle-gun.

The one I bought is lobular, bi-hex. I used a rattle-gun to remove the rear wheel socket on my Mandello S.

News update. What i didn’t realise was the manual says M60, but its actually referring to the thread size. Just put a vernier caliper on the nut, and it’s actually 65mm.
Thank you to everyone who reponded.
I now have a much great knowledge on what socket i decide to buy.

In the workshop manual under special tools (page 89) the last entry states “65MM commercially available” for the socket required for the rear wheel removal. IT then shows a drawing of a generic socket of this kind. given the torque specs for the rear wheel nut are 260 ± 39 Nm (191.75 ± 28.76 lb ft) then perhaps an impact grade socket of decent quality with 1/2 inch drive might be best suited.

Probably worth getting impact as it may be needed to loosen the nut using impact gun.

I did buy a impact socket. I also bought a britool 1/2 torque wrench, the biggest they make in 1/2 drive.
