Why do you want the dedicated enduro bike for an adventure bike? You are asking for more maintenance and more problems. I want to make an SM out of the 450L. I'll take a little less maintenance and problems over a couple extra HP.
EDIT: There is also the rally version of the 450, much closer to an adv bike.
I was going to make a thread asking about best places to go to get my bike serviced. However this has convinced me to invest in some basic tools and do it myself, its easy enough.
