They are no longer the smoky polluting motors they used to be. They are making them that are "cleaner" and more efficient than 4 strokes now, but because they have this rap sheet nobody will buy them. I have them in all my jetski's, and I can have them rebuilt (do it myself) for under $200, do that in a 4 stroke if something blows up. I am willing to bet that new little 4 stroke that Yamaha is putting in the Zuma is as clean as they are in their motorcycles. I just hate hearing people bash scooters and 2 strokes when technology has come a LOOOONG way. Here is one article if people are interested. I could find more, but don't feel like wasting my time.

I worked as a 2 stroke engine mechanic for a bicycle/motorcycle shop back in the late 70's early 80's and can attest to the air and noise pollution of these engines at that time. The engine described in your link is
one example of upgrades made in the technology. I'd like to see the engine reviewed by a 3rd party to prove the claims made by the manufacturer.
My final word on these is either get a 4 stroke motorcycle and learn to use it properly or become a better bike rider and don't go to the gas powered motor- but if the latter truly is not a possibility, for whatever reason, do yourself a favor and get a decent, well made motorcycle.
