So the tires are installed. The front scooter tire 110 vs 120 is pretty big difference. Good note? The speed is off 5 mph even now instead of 3. Those factory tires only went 2282 miles. The handle bar shake is GONE. Yay! It rides so much smoother and the braking seems better? Maybe its just me. It's a little loose in the s-turns right now, but I think that is because I don't have 100 miles on them, need to get the shiny off of them. But I think they will work fine. Next time I'll match the front with the rear tire. I found my info out too late. I didn't think that rear would fit on the front, but according to your posts I guess it does.
