A couple of thoughts on a Honda hybrid scooter.
We do not get out of the USA much, but recently we were in Barcelona. We saw many more Honda scooters on the streets than Honda cars. A hybrid scooter would build on Honda's strength in that kind of market.
While we saw more environmentally friendly utilities in Europe, the environment can take a backseat to what people like, just like in the USA. Europeans might ride high mileage scooters, but they like good acceleration. So they go for two stroke engines, never mind the air pollution. If a manufacture builds a cleaner burning four stroke, they have to offer good acceleration. Does Honda's hybrid scooter offer good low end torque?
