I can't understand it, I'm not a scooter guy. I have 3 little Hondas, a 140 CL90, a 140 CT70, and a new Monkey that are way way faster and cooler, but I just dig riding this little Metropolitan. Even if it can't break 35 mph. It's too nice to mess with and it's really for the wife, so I'll leave it alone. But if I run across a cheap or busted one, I'm gonna buy it and do the 150 GY6 swap.
