New Honda Adventure Scooter
 

Just a rendering of a Honda scoot planned for the Asian market. I hope we get it too. Has taller knobby tires and more ground clearance. Hope you read French.

I think I'd just get a Honda Grome

I would have my doubts about that. I would think belt drive and knobby tires would be at odds with each other.

"I think I'd just get a Honda Grom".
The Grom is more suitable for off-roading, but I live in a wet climate and prefer the splash protection offered by a scooter for commuting.
"I would have my doubts about that. I would think belt drive and knobby tires would be at odds with each other."
I wouldn't use an adventure scooter like a KTM dirt bike. I would use it to detour down dirt roads and utility corridors to get around the traffic jams and accidents.
The larger diameter knobby tires wouldn't be as likely to sink into the mud on dirt roads.
