Okay, so I finally had an opportunity to drive my brother's around for about 20 miles or so. Forgive the non-technical review, as I'm most familiar with the 9er, I'm going to try and use it as relative point so non-owners who care, sorry
Exhaust\Engine - not what you would expect. The apparently aluminum canisters do not give you the trademark Harley sound, which is a bonus to me. Not too loud and relatively menacing. Nice sound. The bike still shakes a bit like his Nightster did (a little less...like they attempted to balance the engine and gave up halfway through). Unlike the Nightster's lethargic rev, the throttle is surprisingly responsive though nowhere near the 9er (as you would expect).
She's a five speed, but the gearing is done relatively well and I was never REALLY missing the 6th gear, even while at 80 MPH. Would have been nice, but without a windscreen, not so pleasant at that speed anyway. 75 felt like a dream. Good acceleration, geared differently than his Nightster which was all torque, this one gives way to more of a usable top end. My bro says he can get the front up without too much hassle and that the suspension is tight enough that he can get the thing airborne on speed bumps...I didn't confirm this personally.
Suspension/ride - The ride is comparable to the 9er in stiffness and it cruises effortlessly at all speeds. I've heard the 9er called a brick before - THIS is a brick, be it one that grabs the road on twisties pretty well, though you feel the heft at low speeds. The riding position is like sitting in a barstool...that's the best way I can describe it...your legs are slightly tucked behind you and relative to the 9er, the handlebars are a bit closer and higher.
Overall, I really like it. Great smiles per mile, and a beauty to boot (I LOVE orange, though). Hoping to get an extended tour with her once he is looking for variety (he always looks the 9er's way). With a windscreen, we got ourselves a good little day tripper.
Money talks though, right? If I were in the market for a bike in that segment, would I spend my hard earned dollars on one? Yes. Definitely worth a look.
