My wife is really jonesing for a scooter. But she doesn't want a 2 stroke. So what do you all know about 4 stroke scooters? - Reliability? - Brands? Vespa clones? - can they be souped up? I think my wife would want something that would do 45mph. Me? I want it to do 65 - 70, just in case. So far, I'm aware of the new Vespas (ET2 and ET2) but they're really pricey. I've seen this scooter clone (Bajaj sp?) that on the surface looks nice. What say the intelligentsia?
