One needs to remember that the "Adventure" segment is mainly a genius marketing branding tool that makes us keep spending our money.
Since it is a constantly growing market every manufacturer with his definition of it and with his budget for r&d.
I too own an "Adventure" bike, its a great bike, but the longest ride i had on it was a 4 days ride.
On the other hand i spent 6 month riding India on Royal Enfield in the early 90s' and it was a great adventure. Circumnavigated Australia on a XT550 with a duffel bag strapped to the rear rack.
What you are seeing are trends dictated by the marketing departments.
The adventure is in your head not with our constant chase for the perfect "Adventure" bike and the perfect "Adventure" gear.
