There is one another problem with scooters, not discussed on forums. They are not the best vehicles for emergency stops.
Anything above 25-30 mph and they tend not to stop or slide in a straight line, but the front wheel tends to slide sideways and you're on the ground.
This effect is even worse in wet.
It is quite terrible on my P250S. When I mentioned that, I got some advices like this was my first scooter: check the tires, check the rims, check the wheel alignment... all this is in perfect condition. I think the problem is in combination of poor suspension and brake components used on ALL scooters compared to motorcycles, weight composition between axles and the fact that engine/transmission do not weigh equally on the sides of horizontal axis, so in case of wheels locking, it tends to pull more on one side. This phenomenon was very noticeable with standard Vespas.
Anyway, I was quite disappointed with this fact and my (then) new P250S, so I have adopted different driving style, keeping more distance and lowering speed. I do not joke when I say that I drive P250S in wet like I drove Piaggio Beverly IN SNOW. It has so poor suspension and braking characteristics.
Even the cheapest motorcycles are better in that regard than the best scooters. I would prefer emergency stop with motorcycle any day compared to a scooter, not to mention the ability to change direction better than scooters etc.
