To Farmboy , its something like leaning on a normal scooter. The thing is like.... You have to lean alot in order to really turn while leaning. For example , a bus and a bike. We will take the bus as the 6 wheeler scoot and a normal scoot as the bike. A bus is more stable then a bike but when moving on only 2 side wheels , the 2 other side wheels trys to pull the bus down as there is weight there and so it is hard for the bus to move on 2 side wheels ( scoot rider leaning ) .
If the bus wants to really move on those 2 side wheels , it needs alot of weight on the side of those wheels he wants to be moving on ( like the rider ) and because the bus has so much weight on one side, it is very easy for it to slide out / rider losing control. A bike rides only on 2 wheels and so what ever way you lean in , the weight is going only at the center and cannot go anywhere else. That means it is more stable to lean on a bike then on a bus.
Shit I typed so freaking much and you might not understand. In my discribtion , in some parts I use scooter rider , bus , bike and all . I'm trying to show that like the 6 wheeler is a bus and a normal scooter is the bike.Grr sorry.
