Quick update:
I picked up the bike today, and I am very impressed. It is interesting how different it feels from the Rockster, although they are similar bikes (naked). Here's what I found:
- Ergonomics are still pretty relaxed, more so in the arms than the legs. The legs do feel more crowded than on the Rockster.
- Engine has a ridiculous amount of power.

I am still breaking in, so no more than 7,000 RPM. But, who cares? Ha ha, it feels like it can go on forever under 7k RPM and still be super fast. Serious now, I can't wait to try it once I can hit the rev limiter.
- Engine has enough low-end torque, but, unlike the boxer, it does not like to be in the 1,000 to 2,500 RPM range. The Rock can cruise all day long at 1,500 RPM, but the K12R gets a little irritated. She coughs up a bit, makes some strange noises, and begs you to keep at least above 3,000 RPM.
- Handling seems to be superb. I like how it enjoys leaning, and how easy it is to get to your balance point in a turn and do it smoothly. It feels great. Must have something to do with the low center of gravity, and even the lower seat that it has.
- I love the oil level straw! So much easier than that tricky window in the boxer! Plus, apparently it won't guzzle oil like the Boxer does.
- Gearbox is great; I love the wet clutch, and the gears seem to click into place quickly and precisely.
- Ride is definitely harder than the Rock. You do feel those bumps right in your butt, and the thinly padded seat does not help.
- What's with that helmet lock? That thing is stupid!!! I already miss the helmet lock on my Rockster.
- The bike definitely feels lighter than the Rock, although it really isn't. I think that the narrow position of the legs help that feeling.
- I love the instrument panel, it's very clear and the fuel gauge is a great upgrade from the Rock.
