I think I need to weigh in here, why not, I'm no expert and that makes me uber qualified, no?
I've wanted a Tenere since I watched Stephan Peterhansel win the Dakar with that big blue awesome Yamaha two-wheeled chunk of unobtanium way back when. I knew of the 750 that came to Canada in the late 80's and wanted one so badly I almost sold a testicle to get it. Lucky for me, no one was buying as I think I may have had more fun with that in my early 20's than I would have a wicked cool motorcycle. But I digress...
I currently have a '14 1190 Adventure cuz, well, my blood runneth orange of late. I've also put over 60k on an '06 V-Strom 1000. So I have a little experience to compare my newly acquired Tenere to. Just a little.
The KTM is quicker, lighter, has far better suspension and really draws in the chicks. Ok, a few guys I know really dig it. Close 'nuff, right? It also carries a load very well, has close to 8 liter oil capacity and is super easy to work on. Ready to Race means that stuff comes off and can be replaced quickly it turns out. Lucky me! But, it isn't comfortable 2 up (for me at 6'6" and my wife at 5'10") and it doesn't have very good wind protection. I prolly should've picked up the 1290T but I got a deal on this one, so it's what I have.
The Suzuki wasn't nimble, wasn't all that fast, had horrible suspension (did I cover that with nimbleness?) and felt like the frame was flexing like an old BMW r-bike in just about every corner. But it was comfortable. It had great ergo's for the two of us and wow, could I load it with crap. Probably the single biggest reason it handled so poorly. Maybe?
The Yamaha is everything I want in a bike like this (big, adventure tourer type). It's comfortable, has shaft drive, it's comfortable, it does 100 without feeling like it's going to shake apart at the seems, it's comfortable, it's smooth, it's comfortable, it has room for the two of us and most important of anything I could think to mention, it's got wicked cool headlights! (bet you thought I was going to say it was comfortable again)
It's been said that the Tenere 1200 is the "Japanese GS" and I like that comparison. I'm not a fan boy of anything. I like what I like and I could care less about loyalties. I loved every GS that I've ever ridden and would really like to own a new one. That damn price and BMW's seeming desire to build out any ability of the owner to maintain them is just damn wrong. So screw BMW, I'll own a Yamaha and be damn happy about it.
