Inner clutch hub nut size for 2020 Beta 300rr

[Johnr37us]

I’m going to put a Rekluse Radius CX in my 2020 Beta 300RR and I wanted to make sure that I have the proper size socket on hand. Would anyone happen to know what size the nut is the holds of the inner hub ? Also if you might also know what the torque specs are for that nut. Thank you, John

Don't know the nut size. My manual just says M18x1.5 thread size. My 2018 manual says 120 Nm torque.
