Question, is Adventure just the new name for Enduro or '6 days'?
Does it have Enduro knobbies?

Google "Adventure bike" and have a look at the pictures. It's basically a long-distance touring bike, with a design nod towards off-pavement riding. Like something you'd want to ride up the Alaska highway or some gravel road to Hudson's Bay.
I think it started with the big BMW twins and spread from there. Now there's an adventure version of many bikes from 250-1200cc. Definitely not a dirt bike or an enduro, although a few start from the dirt-bike end of the spectrum and add a fairing and whatnot to become "Adventure." Like the CCM linked above, or the old KTM 650 adventure, or maybe KLX650. But I think most start out as street bikes that get adventurized.
None will have proper knobbies. Closest would be those TKC-80s posted in rrocket's second Honda pic. Basically a 50/50 street/dirt compromise.
