or go a size bigger to be hwy legal and 150 could be your ticket, I go to get my milk and beer on my scooter, then I go to work all week and get some where in the 70-90 mpg range so my gas spending gas gone to less than 5 a week and more important, my GOOOD mornings always are!
Keep your harleys, they are something different, scooter are not for everybody (just like motorcycles) so barrow your wife's 400 and see if you like it! and then buy what every it is you feel like owning
KLR 650 my one and only!!
