If this is your first ever bike I'd tend to recommend against that ZX6R. Why do you suppose the fairing's scratched & it's for sale? Maybe someone bit off more than he can chew, so don't be the next person to make the same mistake on that same bike!
The Ninja 250 is fine for urban combat...
If you're talking about the Can-Am Spyder, I myself don't consider it a motorcycle because it doesn't lean and you don't use the same physics as you would on a real bike. Even sidecars are closer to motorcycles than those.
If you're talking about the Piaggio MP3, hell yes it's a "bike"...
It's less expensive to build more of one design than less of two designs. Economies of scale. At least you're not saddled with those STUPID politician/mobocracy mandated 85 mph speedos.
While H-D isn't everyone's bike of choice, they are one of the best selling brands of bike *in the world*, so no, they aren't any longer in danger of dissolving. Plus they have all the merchandising profits to boost them in hard times. Now, if only more of their dealerships pulled their heads...

The reason your laptop battery takes 1 hour+ to charge isn't because it's soaking up so many Amp*hours (a unit of energy) but because it has to do it slowly enough that it won't heat up too much by getting charged at too high a rate (energy / time = power). Heat can damage batteries. So you...
The only people that may consider vehicles to be investments are:
1) The manufacturer.
2) The dealership.
In these cases it's also called "inventory".
