I got no where near that mileage with my scooters Indian 75CC @ stroke and Honda Elite 80. but I can tell you both had a little over a gallon of fuel capicity and there is no way I'd want to be riding them for much more then a full tank. Even the 2 stroke 75cc which had the worst mileage and was fastest would run for an hour or so @ 50-60mph and you'd have sore butt when the time came around to re-fuel.

I've been on a couple pretty serious 2 stroke scooter rallies and every time I was happy to get to the destination and drink beer. All this talk however I am longing for the waft of oily exhaust. (I'm not logical like loren it's all about the experience for me) The elite 80 was an amazing machine but had no soul, it was too good.
