I'll add my 2 cents. The Yager is a great little machine. It's built solidly, is very reliable, has low operating costs, low insurance (I only pay $88 / year with Geico!), and maintenance is a breeze (although, as with all cycles, things are a bit cramped).
I'm just over 5000 miles on my Yager, and the only problems it's given me so far is a stripped bolt hole on the oil filter cover (easily fixed), and it recently burped battery acid all over inside the battery box (not sure why, still monitoring the situation to try to figure it out).
You didn't say how tall you are. I'm 6'1" tall, and the passenger hump on the seat tends to push me forward, so on longer rides, it starts to feel a bit cramped. Not because there's not enough room, because there's still plenty of clearance for my knees, but because there's no way to stretch out your legs completely straight or put your feet up, as I used to be able to do on my old Chinese scoot. My restless legs don't like being in one position for long periods of time.
I only commute about 10 miles per day, round trip. If I were doing 60 miles, I'd go with a bigger scooter, just to get the legroom so I could stretch my legs out once in a while. If you're shorter than 6'1", you might not have this problem.
As for the speed, not a problem. The Yager will handle 55 MPH roads and barely break a sweat. I take mine on the freeway, where speeds are upwards of 75 MPH. It keeps up, but just. I'll be adding Dr. Pulley 19 gram slider weights in the CVT soon, so my fuel consumption should decrease a bit, and my top end speed should go up by about 3 MPH.
As for the Kymco warranty and customer service, I can't speak about those. I've never had a warranty issue, and I do all my own maintenance. Just find a good scooter shop who'll do the job right, and you can't go wrong. But beware, there are a lot of bad scooter shops out there, as I learned on my Chinese scooter (they hooked my blinkers up backwards, so when I wanted to turn left, it indicated right and vice versa!)... which is *why* I do all my own maintenance now.
As for how service friendly the machine is, I'd say very. Changing the oil is extremely simple, as long as you've got the right tools. Heck, even adjusting valve clearance shouldn't take you more than 45 minutes.
When the machine is new and the engine is still breaking in, you'll be changing that oil A LOT. I changed mine at 50, 100, 200, 400, 800, 1400, 2000, 2600, 3200, 3800, 4400, and 5000 miles. I started using synthetic motor oil at 1400 miles. Basically, after break-in, with the miles you're riding, you'll be changing the oil every two weeks. AFTER you've broken in the engine, I'd invest in an oil sucker to pull the oil out (so you don't have to even take out the drain plug... just stick the oil sucker tube into the oil filler hole, suck out the old oil, pour in new), and change out the oil filter every two months. My oil filter never looked that bad, even after 600 miles, but it's cheap so I change it anyway. You can get away with changing it every couple of months. When the engine is still being broken in, I'd do the full monty on the oil change / filter change each time just to be sure you're getting out all those metal particles. You'll be able to tell when the engine is fully broken in when you don't see very many metal particles in the oil anymore.
Be sure to break the engine in the right way to get good ring seating... you'll have more power, less oil usage, and longer engine life from doing so.

With as many miles as you're going to be putting on it, you'll be going through a good amount of fuel, so I'd recommend putting a fuel filter on it from the get-go to keep your fuel injector clean:

I'll add more if / when I think of it.
