In your opinion what are the weaknesses of the 390? I have a ktm690 and a beta 200 but i really want to do the tour of Idaho but i live in western NC so I do a lot of similar riding as you. I looking for a bike i could do that trip on and enjoy here.
I think the 390 would be a perfect bike for that. I've rode all sorts of different terrain on it and it does wonderful. I have even ridden it to work and back a few times as well (7 miles of backroads) and it does great. I don't think you would want be cruising down the highway for an extended period of time without changing gearing but it works just fine. It's practically street legal out of the box too. The only weakness for me is when it comes to dead engine starts in harescrambles (takes a few seconds to light up) and the fact that it doesn't come with a cooling fan from the factory, which is not a big deal really as they are easy to install and not that expensive. I would also recommend getting a bigger fuel tank if you plan on doing the tour of Idaho on it. Oh, and if you plan to put pannier bags on it, some makeshift heat shields for the exhaust would be much needed. Cheers!
Do you have any problems in the Enduro with the lower ground clearance? I’m looking at getting a 390 and just realized it has a little over an inch less ground clearance than my RM 125!
