A few on the other forum I follow (I know, I know, blasphemy!) have big scoots, mainly Honda stuff as it's s Honda forum, and they're very capable. I did Lands End John O Groats last year on the Himalayan, three of us did the up and back with various forum members joining us for parts of the trip and one person who did the whole trip was on a 300 Honda scoot. The other guy had a 350 Enfield Classic and the Scooter was not only the fastest of the trio, it carried the kit easier and had better weather protection.
If you do go for one I would go for at least 125cc as they will at least allow you to keep up a with 50/55mph A road traffic, an older 90 is a fair bit slower. Something like this SH300 Honda will top 80mph and the bigger wheels make it feel more bike like.
Being back on two wheels, regardless of style, would be great
