Scooters are excellent. I would love to grab an older PX150 and just have something that the girlfriend and I could tool around on carefree.
I rode a Vespa GT300 the other day and was floored by how comfortable and powerful the bike was. Actually could not hold on hard enough if i pinned it.
That said, the RD250 output is STAGGERINGLY higher. If you're looking for a 50mph, that's overkill. Let alone it's way heavier and harder to manuever compared to a scoot.
Anyone who is saying don't ride a scooter, ride a moped or a motorcycle, is missing the point. Different tools for different tasks. I like them all
