Errr, no. I had one R1200gs which I bought for £4k and only bought because I knew I wouldn't lose money on it, which i didn't. It had 50000 miles and was fine at first. In fact it was the perfect touring bike capable of anything on the road. It was comfy and had power... then the fuel economy gremlin kicked in and fuelling was all over the place... then the brakes (solenoid) packed in, then the power died and I fitted an Odyssey. Long story short, I lost faith and got rid of it. (lost nothing).
Objective means that. Your opinion is only your opinion and in your case seems entirely biased by your own experience, you appear blinkered to anything outside of your own sphere of consciousness. I read a great many opinions, most I ignored as irrelevant for whatever reason but I sought them out nonetheless. My bike has been built to my own requirements. I paid £3k for mine and spent £3k more. That includes luggage, sat nav, exhaust, shocks and other crap. I chose to keep it simple and cheap. My choice.
Objective means the opposite of subjective. That means you have to speak beyond your own experience and the fact is that very few G650gs (singles) fail globally. As bikes grow older they wear, shocks are a wearing component and prone to failure. Truth is, BMW fit crappy parts sometimes (not all the time, the Challenge has a good shock that is just a typically German conceptual design failure but could just as easily have worked well).
I would never tell the OP, or anyone else that their question is stupid but only encourage them to try within their boundaries. Certainly I wouldn't comment that the forks are just barely acceptable if you're not fussy which is the way you speak of other peoples machines. So you spent £2700 plus £4k kitting it out? You ignored me when i asked on ADV when I was trying to work out my budget but hey, I did it and I'm doing it. I met a dealer who had to come out and go over my bike because it was so different. I like that. People come up and ask questions (police sometimes but hey, life is short).

I say work within your boundaries. Everybody's opinion is just that... an opinion. I think the G650gs is a great little bike capable of RTW action if you go in with your eyes open. It's a brilliant machine for the price, not a hardcore enduro capable of massive abuse but a good bike that will survive some hardship, probably more than most riders can endure. I say most people have an opinion unfettered by logic, based on emotional alpha-brain unthinking bias.
Opinions differ. I think some of my solutions are far better and I disagree with solutions of others but my opinion is just that... an opinion. For instance, i put my spare fuel at the front of the bash plate and can logically explain why that is better than an X-tank. Some people disagree. That's what it's all about. If people agree then there is no discussion and it's a quiet, boring little world.
