I have a 2010 1198S with 5,500 miles on it.
After a ride, the outside of the rear hub feels borderline very warm to hot to the touch. I can keep my hand on it for a few seconds but it feels a bit hot. The rear brake rotor and caliper are not hot and the two screws for securing the eccentric adjustment are torqued to spec.
I am sure some temp increase is likely due to the power being transmitted but is it normal to feel a bit hot?
I also have a Sato crash protector going through the axle, maybe that impedes some ventilation?
Thanks for any thoughts on this issue.

First thing coming to my mind is bearing(s).

I just pulled my rear hub apart for a service/inspection.
I could get the inner race out to look at the sprocket side bearing but could not get the other side bearing apart to have a look.
The bearing I could see looked good and I just put it all back together.
Not sure how hot the hub should run.

Could end bad if that hub fails.

If you have access to a thermal imaging camera, it will tell you what's going on.

Don't think they are meant to get very hot.
Just check it on shorter rides. If it's hot to touch after 5-10km and gets hotter with more km you could be looking at a ceasure or wheel falling off.
Does the wheel spin smooth as or can you feel any thing.
Will check if they get any warmth when I next ride mine.

Make sure your chain tension is set properly. If its too tight, it could cause unwanted preload on the bearings. How many miles on the bike?
