Congratulations on the Katoom! It's a beaut!
That's a myth.
The final drive is prone to fail in all sorts of stuff, tough or light use. Some guys will beat the crap out of it through mud, water and sand day in and day out and never experience any problems. Other guys will take it to Starbucks on the weekends and get a final drive failure. Or vice versa. It's a design issue, not a usage issue.
At some point I want to take this beast into the dirt and I read too many stories about BMW final drive failing in the tough stuff.
