Power isn't a big deal on the XR.
There are truckloads of parts you can buy for it to get more power just about anywhere in the rev range you want.
The basic platform is great. Any bike needs to be fit to a rider, so I wouldn't sweat the griping about tripworthiness so much.
It does take some grit to tour with it, but that's why they make Goldwings and 883's, and touring accessories for both.
I love the XR12. I haven't yet met anyone who has a legitimate gripe other than mechanical failure that couldn't be addressed with $ and smarts.
"If they would have made this 15 years ago... Well, I would have killed myself to death actually. But what fun while it lasted.
