I'm in Oz and we are lucky enough to get access to a lot of big single adv bikes. I currently have an XT660Z Tenere, prior to that I had a 2011 G650GS and prior to that a 2011 KLR. I have bought and sold each of these bikes in rapid succession looking for the "right one".

KLR: Tall and heavy, but has a carbie and therefore no surging and easy to live with. It's old skool but I would have another if I had to. Hardly any vibes. Didn't have the "wow" factor

g650GS: Good allrounder for me. Commuted beautifully, lower seat and hardly any vibes. Had no buffeting problems but head was always in the wind. Didn't have the "wow" factor

Tenere: Vibrates like a ******* but only had 2100km on it when I bought it. Has over 3000km now and seems to be getting smoother!? Throttle is surgy and annoying but I am getting better at rolling on and off to smooth it out. Very tall and heavy with a full tank but I am surprised how more balanced it is than the KLR under same conditions. Newer design and technology than the other two. Looks as sexy as hell and definitely has the "wow" factor. I am really starting to love this bike and look for reasons to ride it, even around the neighbourhood. The screen is very good but wind comes up through the forks and buffets your helmet around. I had to sell my AGV AX-8 because its flimsy peak vibrated right through the helmet, through my earplugs and into my brain. Didn't have this problem on the other two bikes but I also don't get as wet because of its better wind/rain protection. Solved the vibration/buffeting by getting a Fly Trekker helmet. Will also put a bar bag on to break up the funneling wind a bit more

I am a 177cm 5'10" tall very new rider so the Ten is a bit threatening to me with it's size and weight but I love riding it and while I do almost all road riding I do get out and enjoy dirt roads and smooth tracks. Not skilled enough to go any harder but that's why I bought a 660 single - so I could ride for ages and check stuff out at a leisurely pace, while still pick it up if I went arse over. Sits on highway speeds all day long.

Get the Ten. You'll love it and it won't break down. Farkin' expensive though for a single here in Oz because it's made by you highly-paid Europeans and not in a Japanese factory. Every time I look at it I go "phwoar that's a nice bike."
