It SEEMS like the market is untapped. Scooters make a great deal of sense in the American market, but no one has found the formula to sell them. The wave of awful generic chinese imports hurt the idea of the scooter, and the stigma that all riders are actually DUI's on suspended licenses keeps some people from showing interest.
Kymco builds a great machine but seemingly has no earthly idea how to name its machines. Myroad, Bet and Win, People.. terrible marketing. Sym went through its importer drama and will take a long time to repair, plus there is the Lance/Sym confusion. The Symba was a great idea, but now discontinued. TGB is back.. once again. Of all the Taiwanese scooters I see in my town that I can identify, its generally Genuine Buddies, but the local BMW/Triumph dealer just started carrying Kymco so that might change locally. I don't think any marketing revolution in America would come via Taiwan.
Vespa people are Vespa people. The world doesn't seem to be suddenly making multitudes more of them.
There needs to be a UJM of scooters. Powerful enough to get on the freeway when needed, cheap enough for anyone to buy if they save a few months or have remotely decent credit, and looks really good on its own right, not pretending to be a Vespa and not looking like someone had it shipped in a crate. I Piaggio BV350 and the Honda Forza 300 get pretty close, if not perfect to that idea. But how often do you see them on the road? I think the market is pretty well tapped.
Maybe as batteries get even better and wheel hub motor prices come down we'll see cheap fast electric scooters really get their chance to be more than toys. That might have an effect. Some states have some pretty good tax rebates so that could cause some movement in the market.
