It depends on the scoot. The Yamaha Morphous is very' huge. Looks like a big blue orca but is one sleek machine. I cannot imagine that would be an easy machine to maneuver.
My ride is made by Flyscooters in the Znen Motorcycle Factory in China. Of all the China-made scoots, Flyscooters are right at the top in quality and customer service. There are some scooter "snobs" who look down on our China-made scoots because they do require more maintenance, but their value far exceeds their cost or the "trouble" of having to have the engine oil and gear oil changed after the first 350 miles, then again at 500 miles, then every 500-800 miles after that, depending on your climate and how hard you ride. The engines are 4-stroke air-cooled with a CVT automatic transmission. But even the scooter snobs who look down on Chinese scoots give props to Flyscooters. The scoots coming out of China since 2007 are made a lot better than they used to be and are overcoming some of the bad rap they've had amongst the Vespa and Lambretta and Yamaha enthusiasts. My bike is a 2008. They are usually available for sale in California the year after they come out (getting that C.A.R.B. certification takes a lot of red tape, aaprently), so my bike was brand new when it was first purchased in June of 2009. I am the second owner and have had it a little over 2 months. It is the 2nd scooter I have ever owned. Had one when I had my first 'real' job shortly after high school, rode it about a year, and have wanted one ever since. Having little ones kinda precluded the practicality of having a scooter, but the last of my offspring fled the nest last year in February, and Mama is finally free to ride!
Znen also produces scooters under the brand names of Lance, Eaglecraft, BMS, and one other but the name eludes me at the moment (I have Sometimer's Disease). They are very similar to Flyscooters. They are a good value for the dollar. You can get one brand-new out the door (it's a 150cc automatic) with a 1-year warranty and 5 years of free oil changes, complete with a helmet and a trunk, for just under $1,500 here in Sacramento. And if you take care of it, you'll get a lot of miles out of it. Heck, the 5 years of free oil changes alone makes it almost worth it.
I'm pretty small, but I do carry a lot of "junk in my trunk" (gigantic purse, etc.), so figure there's 140-150 pounds on the bike at any given time, and my last 2 tanks of gas have figured out to be 83 and 77 mpg, respectively (hauled a lot more stuff this last round & did a lot more in-town riding).
And yes, we do take cruises along the delta and out in the country, like "real" bikers do.
As far as the handling goes, like I said, I can imagine a scooter like the Yamaha Morphous might be a little hard to handle. My husband has a Jonway YY150T2 that is very sporty and aerodynamic and has more "pep" than my little vintage italian-style bike. I have to say that his bike handles much better than mine. His bike also has 13" wheels, whereas mine has 10".
His bike has the good handling and the pep, but mine has a nifty retro style and is a very comfortable and sweet-lookin' ride. They have the same engine, called a GY6. My bike also has regular 'motorcycle handlebars', while his has 'scooter handlebars'. So each has its merits for comfort and rideability.
If you've ever been curious about scoots, just go to a scoot shop and ride one for the fun of it.
