Last year I rode the Connie, the Ninja 1K and my Versys back to back to back over a road I know very well since I ride it often. I love the Connie. Extremely comfortable, tons of gadgets to play. The electrical adjustable windshield was outstanding at keeping the wind off my head. One thing that I do not know if I hated or loved was the linked brakes. Going hot into a turn I dragged the rear break a bit and was surprised by the application of the front break. No problem really, but it send a message that this was not business as usual. I believe the current model have an adjustment for more aggresive riding. I would also install a bar riser right out of the gate. Although I appreciated the aggresive riding position in the twisties I'm not sure I want to spent much time leaning as much. I understand I can put a 2" riser that will help with that. Right now is the bike at the top of my list for an upgrade to my 08 Versys.
However, the ride in the Ninja 1K was the most fun. The ergos are better for me than the Connie and I could appreciate the handling of the much smaller bike. I say that while the Connie is really good, I felt right at home in the Ninja 1K despite the big difference in power vs. the Versys. If I were shopping for an upgrade just for solo riding I would consider the Ninja 1K. Put a set of hard bags and a top case and I'm ready for touring. However, riding two up is the main reason for the upgrade therefore I will go for the Connie since it offers the best accomodations for my wife.
I would not go and drop $15K for a bike without having a conversation with my wife. We have a very effective deterrent police against trivial expenses. We follow the policy of mutually assured financial destruction. If I go and spend a bunch of money in something without consulting her, she will retaliate with full force, and she would love to be driving a BMW or Audi to work everyday.
