My first response, as a 14-month SR owner, was that the SR would be a great first bike. Electrics are so much easier to operate, so much smoother and predictable overall, that you don't have nearly as many skills to learn as you would on an ICE bike. The power of the SR isn't a problem -- there's no rule that you have to twist the throttle all the way to the stop.
But dkw makes a great point. Until you become truly facile with a motorcycle, your odds of dropping the bike are pretty high, almost invariably at low speed rather than high speed -- speaking for myself, I dropped my first bike twice before I became really confident on it. Motorcycles are like bicycles in that they're quite stable once you're up to speed, with the steering geometry working for you and the wheels contributing gyroscopic inertia, but they can be a handful at low speeds where you don't have either advantage. A truly skilled rider can wait his turn at a stop sign at very low speeds without putting a foot down or wobbling from side to side. That kind of skill takes a while to develop.
After thinking it through, I think I'm going to have to side with dkw. You really ought to think hard about learning on a less expensive, lighter, more agile machine, and look at it as an opportunity to see what becomes available in 2016, as your riding skills are developing. There's good reason bikes like that are considered beginner bikes.
