Wide ratio gears.
It means cubic centimeters it refers to the engine size..
It depends on if you mean quick off the line or top end speed the honda cr is notoriously quick especially with power bands and a smaller back sprocket but for top end speed you need a four stroke

If by "pettle" you mean pedal bikes, then yes, there are pedal bikes in Japan.
no there top speed is about 70 mph about the same top speed of a 400ex i would have to say a Honda 450r , Yamaha yfz450 suzuki ltr450 just because they have more cc's don't mean anything to these bikes{ excluding small bikes}
I have no idea what you mean by a "bmx bikes device".
What do you mean? I can probably answer any question involving Motocross (Motorbike racing) but do you mean how do you participate? Well, the way I race, is I go to big national races, where a bunch of other people race too, against me, but only in my class, (bikes around my size and people my age) and we race dirt bikes, basically some people only race for the fun of it, but some people only race for the prizes. If this wasn't your question or not a good answer, I'm sorry.
-that depends on what you mean by restricted- to ride a 125cc bike you have to be at least 17 you pass your cbt- you are allowed to ride a bike up to 125cc as long as you wear L plates at all times, do not go on motorways and do not carry a pillion passanger
A quad. well if you're brave enough, any smaller 2 wheel dirt bike. i mean 14 is old enough to ride a lot of different motor bikes
Don't know what you mean by a MX bike.
