You should have a pretty good handle on your choices with the exception of the Terra. You have access to a Versys with a 19" front wheel and a XT600 isn't too far removed from the DR and KLR's horsepower wise. How was it? I adventerised a TDM 850. Rode the local fire roads, SE Ca. sand and the Alpine loop in Colorado. 6" of suspension travel is just not enough. The world needs a 400lb multi, but I am not holding my breath. The Japanese thumpers will cruise 80mph in Kansas on a calm day. They all need a HP boost and FI sure would be nice at 7,000ft. Suspension mods are a given. They do get tossed a bit in gusty wind. The lighter and taller they are, the worse it gets. My situation is similar to yours, living next door to 2,500 miles of fire rds in the Stanislaus national forest. My weapons of choice were a F800gs, that still needed $2,000 in suspension up grades and a KLX 680, a more dirt orientated KLR with a HP boost from the factory. With a big bore and all the other tricks, I am still searching for more HP for the road. Like a proud parent, I like to show it off. My advice is to go test ride the Terra and decide for yourself. It sounds like a pretty good highway compromise, it is the dirt portion I would like to test. The dyno says it puts 48hp to ground which is what I think is acceptable. The above bike is close, but no cigar......yet. The China connection? It will keep coming up. BMW and Loncin have long term connection. To the best of my knowledge, Rotax no longer makes the F650 engines or parts. Loncin had assembled Rotax parts for several years but now manufacture the complete engine starting with the G650 bikes. They have used that engine in their own bikes under license to BMW. Loncin did not design this engine, it is still based on the Rotax engine. This one has some newly designed parts, so maybe those are made elsewhere. Just like the assembled engines, they are shipped back for final bike assembly. Loncin is the worlds largest motorcycle engine manufacturer. The plant is huge, modern and highly automated. I would not worry about quality and like it or not it is more common place than most buyers think. Adv Grifter is correct about cost of one. It only starts with buying it. You will have to consider wind and bike protection.
