My meaning it is..... depending on what you need or what you want. I explain:
If you need something to go quickly from home to the work, to make some business along the day, if you have problems to park, if you have to go to the center of the city, you need a scooter.
If you want to make big rides, hundred of kilometers or miles, you need a big bike.
For now, my driving license only alow me to take motorcycles up to 125 cc or 15 cv. This means what if I want to buy a bigger one motorcycle, as an Harley (that's my wonder), before I have to spend a lot of time and money trying to get a new licence.
I work at 12 km from home. I have to make many small business frecuently, at the center of the city.... I needed a scooter.
So, here in Madrid, the laws allow the bikers (independing of scoot, bike, etc.), to park over the sidewalks everywhere.
There are only a few conditions:
The sidewalk has to be at least 3 meters wide. You have to park parallel to the road. If the sidewalk has 6 meters or more, you have to park "in battery".
Other condition it is not to park close the bus stops, the pedestrian crosswalks, etc.
Responding this item, I don't need more engine power. I prefer big scoot, small engine.
