I'm kind of the opposite.
I've never owned a Harley and don't really intend to. Not that there's anything against them, just that this bike is so much fun and everything I'd hoped it would be, and it fits me better.
I also picked up a new '16 on sale (huge discount), and what's so appealing is the ergonomics, the "feel", and the ability to readily tour. It's quick, looks great, and rides well (although I did replace the OEM tires at the 600 mile service).
My wife has a couple of Triumphs (Street Triple R and a Daytona R), and neither really fit me. The Ninja out-handles the Street and I find the CG on the Daytona odd (very forward). I'm not entirely sure, but on the street I think I out-turn it too. And this Ninja outruns both, hands down.
But the Harleys I've sat (and I could be wrong), all position my feet way forward, so that, oddly enough, I feel hunched over leaning to get to the handlebars. For me, after sustaining a lower back injury while in the military, that kind of hunching isn't comfortable. Around here, Harley rules, no doubt, and I mean no disrespect. It just doesn't fit me and the style of riding I do.
The Ninja, moreover, isn't your typical crotch rocket. It's a sport bike, to be sure, but the grips are elevated just enough that you're not hugging the fuel tank. Your feet are below you, instead of forward or behind, so it's a more natural sitting position. The CG is low and centered, so turns are honest and true (again, ditch those OEM tires and go with a 55 on the back). And doing, ahem, 80 or so on the freeway puts you just over 6000 RPM, so you can ride all day long and your bike is happy to do it. Not that one wants to ride freeways all day long. Just sayin'.
And if on sale, that's a heck of a deal.
I got mine for $8500 OTD with 3 miles on the odo. I had to drive 200 miles to pick it up, and I'd intended to trailer it home since I would be driving in Chicago traffic on a very windy day, and putting 200 miles on an unfamiliar and new bike. The trailer idea didn't work out (wife absconded with it for her Daytona), so I rode the traffic, wind, and distance, and loved every minute. Jumped off the bike and would have happily done 200 more.
On the quality side, I've read here a couple of reports of issues with new Ninja's, but those seem to be very exceptional. It's built solidly, yet all sorts of customizations you can perform if so inclined (me, LED lights). Mine's been awesome since the first mile.
I'm sure whichever bike you decide upon, you'll be very happy. I can say, with certainty, that this Ninja will make you smile when you ride it. Hopefully you can nab a test ride and know for sure before plunking down a ton of cash. Even if not and you take the chance, I'm hoping you're as happy with yours as I am with mine.
Yours was a great post, by the way. Welcome to the forum.
