My 750 only costed me $3k, had 3,5k miles on it.
The 229cc is 2400 delivered, 2600 taxes included. Your Aprilia costs 3k + dealer fee + taxes, which is closer to $3,5k.
That's $1k more than my 229cc, probably performs better yes.
I pay no insurance, not necessary in FL; only a tag sticker every year. I only have 2 tags, do illegal by swapping them, but for the most part I only ride 1 scoot, and 1 motorcycle. I only take out the others every month to get the battery and gas going; or like right now, because one motorcycle needs a new bearing.

I have the same shield on my ATM50 too!
It's true that it's not meant for over 45MPH. The shield bends.
Also, the screws and bolts rust.
It's a good shield, but mine is cracked already (got a star or flake shape in it), because of a small pebble hitting it at ~45MPH.

My ATM also had a vibration going over 40MPH. I think it's a belt oscillation with the engine vibrations, and nothing to worry about, as long as the belt isn't dragging anywhere.
A new belt, bando, can be stiffer, and have a higher oscillation frequency. You might still have the same issue with the Bando, only at higher speeds (but perhaps not as high as your scoot can go).

Put the can in your pants, and act like you just took viagra! Otherwise, the glove compartment should be able to host a can. Underseat storage gets hot, but you could also store it in the trunk. On my ATM50 I can fit anything from a medium to a large soda cup from fastfood restaurants. it fits just fine! Here's a small view of the glove compartment:  |

The gear oil on chinese scooters must be changed, as initially the gears and cogwheels chip off small chips of metallic flakes that could eat through rubber sealings and gaskets over time.
If you're not going to change it after 150km and later at 1000km, then do it once at 500km. You'll see how many flakes there are in the oil!
Once you do the 1000km interval, you could run it for the lifetime of the scoot. I haven't changed mine since and I got 5500km on it. I'll see how it looks like, but most likely it has metallic flakes in it.

The aprilias are still a bit on the expensive side for me.
I have the Roketa MC-05-127, goes upto 60MPH. I put another sprocket in that gives me greater gas mileage. it starts up a bit faster than a 50cc scoot, in second gear moves along with traffic normally (does not pull away from it), and in third and fourth is accelerating normally when you rev it high.
It gets 96MPG when going ~60MPH, and 118MPG when going 35-45MPH.
because it's only highway worthy at 55MPH, I needed something bigger.
I made an order for the DongFang MC-D250-RTC-B.
It's a 229cc bike, that probably will get around the same 110MPG at 45MPH, with the difference that it will go 70+MPH; which is good enough for me.
For highway riding I much prefer my Honda Shadow 750 anyway, but as a local commuter, that doesn't look like a hybrid between a motorcycle, scooter, and bicycle like the MC-05-127 looks like.
The DongFang is only $2400 delivered. I'm gonna see if it lives up to my expectations.
As an an economic, MPG monster commuter most surely it will.

I don't agree.
If the problem isn't caused by a worn belt or rollers/sliders, then the next logical step is the gearings.
If the engine is already reaching over 8k RPM, it has too much power to run with the stock gears, and a gear upgrade is needed.
If it is a 75cc BBK, my ATM50 has a 63cc upgrade and reaches to 47MPH, so you should be able to squeeze just over 50MPH out of it.
I'm sure the engine will pull the heavier gear, but I'd say only one tooth higher on the front and 2 or 3 lower on the rear or something).
You got to take out the stock gears, count the tooth, and find something that's one or two steps higher.

heavier sliders/rollers would most likely not do anything, as the variator is most likely already maxed out. Taller gears is the solution, combined with lighter weights, as the variator will be rotating faster.

Nice!
Now only one more thing, which all these scooters should have (like my BMS 260 had) is to have a place on the dashboard to install the GPS on. My BMS TBX260 had a flat surface under the handlebars that could host a GPS, however it's better to have that space above the handlebars.

You could go faster by installing taller gears, and bring engine RPM down by 500-1000 RPM.
At those RPMs the engine does not have sufficient power to maintain those speeds.
Most of those engines are capable of doing 9+k RPM, (you can test this out by putting them on the center stand and revving them high), but at those RPMs the engine does not have much torque anymore, so it's not capable of going faster.

just make sure you double nut those exhaust studs, and have the fuel line clamps connected correctly.
BMS is getting better. The uni rear suspension is the best, although a bit hard for my 160LBS, even at softest setting (on my 260 I could increase/decrease spring tension).

Roughly,
Oil changes on a chinese 50cc without oil filter is at:
0, 50, 100, 150, 300, 1000km, and every consecutive 1000km.
Oil change on a (chinese, non-oil filter) 150cc is at:
0, 50, 150, 300, 1000, and every consecutive 1000km
Oil change for my chinese BMS 260 was at
0, 50, 150, 300, 1000 and every consecutive 1000 miles. (odo was in miles, not km)
Gear changes on all bikes are at:
0, 150, 1000, 3000 and every consecutive 3000 odo readings (miles on 250's, and km on 150's and below).
Taiwanese and Japanese bikes have smaller tolerances, and less particles in the oil due to having an oilfilter. So they can last longer per oil change, often ranging between 3k and 5k miles per oil change.

I could have tightened the rear wheel too much, causing sideway forces on the bearing, causing the balls to eat through the sealing rings and in the end roll out of the bearing.
Not that I tightened it too tight, I just tightened them a bit more than usual, because it felt like it was getting loose.
If they are greased, mines may have been greased with the wrong grease. The few ones that still where in there didn't have grease on them, where shiny metallic balls.

I'm 150LBS , and do 55MPH @wot on my 150cc scooter with CVT. 63MPH on a good day (meaning with some wind in the back).

Not worth it!
Worst case the CDI will tard performance.
It's not going to do a lot about the spark. Want a bigger spark? Get a better spark cable.
You could also gap the spark plug somewhat. Stock gap is 0.024", you can bring it down to 0.015" without probs.
