I think it's changing slowly but surely.
Before I don't believe many dealers thought they would make any $$ from scoots, but now your seeing a lot more Chinese 50's out there. It is the fastest growing segment of the motorcycle market. The dealerships will want a piece of that market, knowing that the little 50cc is not going to serve the purpose of most commuters.
I think the motorcycle marketer's realized that there was not a mid range motorcycle in the market for a long time. Look around now and your seeing a reintroduction of the 250's, the 650's and 700's. Your also seeing a movement towards automatic shifting. Woman are also the fastest growing segment of riders. They need storage and again, now your seeing more storage on bikes. Maxi-scooters fill all those needs.
Increasing urbanization will also drive the market. When you look at the advertising for the BMW scoots it's all about "urbanization." I think BMW realizes that there is a growing market for maxi-scoots and mid-range motorcyles and they want to be at the forfront of it. While America will never be as scoot filled as China, I can see the day coming where motorcycles/scooters will be more common.
Gas prices will get worse. That is a given. While some cars are capable of 50+ MPG, bikes are still cheaper and generally get a higher MPG.
So give it 5 more years. You will see more Maxi's out on the roads.
