So is the only thing you would have wanted differently to make it perfect is more suspension travel/specs?
No. I think the stock suspension is rubbish, but that can be partially solved in the aftermarket. There's a lot that could be solved through the aftermarket on this bike. Some things can't be solved, unfortunately. I think the primary issue is the ergos, which I've mentioned prior. The big issue there is the very long tank combined with the short peg to seat distance (which is improved, but still pretty cramped). You could improve that to some degree with bar risers and lowered pegs. AFAIK there are no substantial changes made to the frame, geometry, or wheelbase from the Scrambler, making this a bike that prefers the road, but further sacrifices it's roadworthiness with a knobbies and a 19" front wheel. There's also no factory luggage option. The tail section remains unchanged from the other 9Ts, so the diving board is still all that protects you from rear wheel fling. There's been no big solution for that in the aftermarket, but some improvements over stock are available. Basic GS accoutrements are missing that would need to be added after market (hand guards, bash plate, engine guards, oil-cooler guard, etc..). I think it's weird that the high pipe is standard on the Scrambler, but has to be added on the UGS which is supposed to be the more off-road capable of the two. As far as I can tell there was no effort made to shave any weight. There's no tach.
Were I to buy this bike, it'd be another $4000 getting it where I think it should have been from the factory. Like I said, that's just me. If someone slaps a GS logo on a bike and tells me it's a modern throwback, I expect the looks to be vintage inspired, but the rest up to modern adventure touring standards. BMW has been in the big bore dual sport business for longer than anyone. They could have easily spent some time making this a proper GS throwback bike.
Anyway, I'm tapped out on this Congrats on your new ride, I hope you enjoy it, make it your own, and have a lot of fun with it. I'm hoping to see people using them on adventures and proving me wrong so I can buy one.
