Does anyone know the rating on gas scooters, as for which are the best?

If you are looking for just around town then a Yamaha BW50. It does 75 KM/h and is a two stroke for acceleration and has oil injectors. great warranty as well. If you do any highway or at speeeds around 85-110 km/h then you might want to look at the Honda Reflex, 250cc and has styling like a sportbike

Check out amazon! I like all there ratings by people!

Google it.

just get a vespa

check mouthshut.com, you might find consumer ratings there. what is a gas scooter? the one that runs on LPG or petrol?

Edit your question to include an engine displacement size in cc's (or at least what your top speed expectations are), and which country.
