So many have taken very long rides on 50cc and up. I prefer a 200 to 225 for my fat ass but to each his own.
Only safety issue is having enough power to get out of the way and I have rode very small bikes on major freeways in Cal.In work traffic that Zumo would be OK but when everyone is doing 70, very SCARY. Balls like a bull moose. Best thing about small bike is when I am on one, time must not be a big factor, that is the whole idea, to go slow and enjoy. Now you can go just as slow on big bike but it is different, as most, including me, when you get tired or bored instead of getting off the beaten path just speed up to get going. It is great to get 70 to 85 mpg also. I painted over the 125 on a Honda to say 175 so I could ride to the Colorado River. Just kept riding on freeways.

Have had many BMWs inc 2 r100GSPD, R100GS, 1150GS, 2007 f650gs Dakar. and about 15 other BMWs, mostly weekends and commuting to work.
These are very small trips compared to thousands who ride small bikes all over the GLOBE!!
Small bikes are great, get one and travel light.
