bigger tires on a Kymco Agility?

I'd already been thinking about this, but I decided to post after reading a review about the Aprilia SportCity 250 that mentions that, "although it has 15 inch rims, the tires have a profile such that the profile used on the tires makes it ride just like a typical scooter with 16 inch diameter wheels". (This one happens to use 120/70-15 in front and 130/80-15 in rear).

That makes me want to consider upping the size of my stock tires to try to gain these 3 benefits:
* Slightly better ride when cruising on roads that are not perfectly smooth.
* Slightly lower RPM when cruising at 50 MPH.
* Slightly more or a lot more accurate speedometer.

Speedo note: According to my math which might be wrong, if our speedometers are off 14% out of the factory, and if our front tire is 58.478 inch circumference stock, it would take a tire with 66.66 inch circumference to make the speedo register correctly, for example, a tire 130/90-12 = 21.213 diameter and 66.643 circumference.

Note: I am willing to experience a slight decrease in power.

So here goes. This is the stock size:
Stock
Front: 120/70-12 = 18.614 inch diameter and 58.478 Circumference
Rear: 130/70-12  = 19.165 inch diameter and 60.209 circumference

QUESTION:So, what  tire sizes are being run on a Kymco Agility? I guess this question could go out to both 50's and 125s.

Note: From looking at the front and rear fender design, I do not see that it would be any problem at to go bigger than stock. All one would need to do is put in spacers on the fender connectors to make a little extra clearance between the bigger tires and fenders. I think the only real blocker is in the rear, where there is really only about an inch of clearance between the tire and engine block.

At this point, I have heard of people running 130/70-12 in front and rear, and that this worked out just fine.

Option 1 - little bigger on front. (this has already been done).
Front: 130/70-12 19.165 inch diameter and 60.209 circumference
Rear: 130/70-12 19.165 inch diameter and 60.209 circumference

This will get the speedometer slightly more accurate, and get a little more rubber on the road in the front.

Option 2: Like just going to 80's. Front: 120/80-12 19.559 diameter and 61.446 Circumference
Rear: 130/80-12 20.189 diameter and 63.426 circumference
Rear clearance math: 20.189 diameter - 18.614 = 1.575 inch diameter difference = .7875 closer to engine block in rear (too close?).

or

Option 3
Front: 130/80-12 20.189 diameter and 63.426 circumference
Rear: 130/80-12 20.189 diameter and 63.426 circumference
Rear clearance math: 20.189 diameter - 18.614 = 1.575 inch diameter difference = .7875 closer to engine block in rear (too close?).

or

Option 4
Front: 130/90-12 21.213 diameter and 66.643 circumference.
Rear: 130/90-12 21.213 diameter and 66.643 circumference.
Rear clearance math: 21.213 diameter - 18.614 = 2.599 inch diameter difference = 1.1995 closer to engine block in rear (too close I think)

I chose Pirelli SL 26 130/70P 12s front and rear. One thing that pushed me to them is that a guy at the Ducati shop said that they were a very good choice for a small rimmed motorcycle.

I'll report back after I get them installed. Motorcycle SuperStore seems to be the place to get tires, etc. Free shipping and it took just 2 days.
