Also you want to vary the throttle often, as in don't just cruise around at the same speed. Also, ride a while and then take a break and let it cool down. In usually do a quick oil change and , in the case of these scooters, check the oli filter/screen for deposits. On my wife's SYM I believe I went ahead and changed oil at about 50-60 miles and checked the screen--it was fine. then I let the dealer do the first service. That was more to not be able to try and void the warranty because they didn't do the first service. Legally, I don't think they could void the warranty if you do the service yourself, but I didn't want to give them any amunition.
The ideal place to break in a scooter or motorcycle is probably just cruising around a neighborhood with lots of stop signs., some hills and such.
Others will chime in here I'm sure.
