When you own a few scooters it's interesting to see which one you reach for and which one just doesn't get used much anymore. When I swap rides, which I do after one or two tanks for gas, the one I start to use feels so very different and a bit clumsy, but after a day it just feels natural again, and after that I start pushing it some and remembering what it can do and will do for me. By the time I've run through the two fill-ups I know why I'm keeping it. Even the two 90 CH250's, that should be identical, are different. They have the same tires, so that's not it. One has a lot more miles, the other feels fussier on city streets about starting and stopping all the time. They fit the same. It's just fun to mess with them.
