I searched, and couldn't find it...
I have the factory s/m for my bike, but the manual is an '00 and my bike is an '02. The torque value in the manual is for a 17mm rear axle, and mine is a 25mm axle. The torque spec stated for the 17mm is 72 Nm, but is it different for the 25mm?
TIA!!!

I don't know the answer, but if the rear is hollow like the front...
I'd use the same value...
which is 63 Nm with greased threads
83 Nm, same as the ST.

No, it's hollow.

Weird that the same fastener on a similar shaft size takes a different torque.

Awesome, thanks for the quick response!!!

From the factory manual:
Front wheel nut M 25x1.25 63 * GREASE B
Rear wheel shaft nut M 25x1.25 83 * GREASE B
No idea why.
I haven't done a calculation recently, but IIRC, chain tension plus forward thrust at the rear axle can be ~1500 lbs at WOT in 1st gear, so that makes sense to me to have more pinch.

Definitely makes sense.
