Am I tall enough to ride a Crf 250r?

I really want a Honda Crf 250r and was wondering whether i'm tall enough or not. I'm 5'6 and 120 pounds. I'm not to experienced of a rider. I also was looking at a yz125 I know that it is a little taller but have also heard that a crf 250r is for the experienced rider. If i'm tall enough for both which one of these bikes would suit me better considering my skill level?

Is a Honda or Kawasaki dirt bike better?

I'm going to get my first dirt bike soon. I'm a "whopping" 4' 9". I want to get a bike with not too much power, but not too little, and want one that usually doesn't break down. I heard that Kawasaki's are better, but don't rely on it…
So, what do you think?

Honda vs Yamaha? For short people?

My dad has decided to buy me a bike. I know nothing about bikes. In fact i'm going to learn how to drive one. He told me he'll get a Honda brand. The budget is 50000-65000. As i googled i came across CB Twister and CB Trigger. My height is 5 feet 3 inches. I ride non gear bikes perfectly.
Also heard good reviews about Yamaha. Please suggest me a bike

1) Low maintenance and good mileage
2) Style and looks
3) In my budget or a little greater
4) Comfortable for me (my height)
5) No body pain

Added (1). I'm from India. Its Indian Rupees not dollars! LOL!

1980 Honda cm400. Gasoline in oil?

I'm looking into this 1980 honda 400 as my first bike. I'm well versed mechanically, on similar bikes and cars as well. The only real issue is that I can clearly smell gasoline on the oil dipstick. The owner stated it will most likely need new piston rings but I saw no blue smoke and minimal white smoke as the bike warmed and idled.
I'm curious as to what could cause this… The carb must be flooding over, through the cylinder etc. There's a small leak in the fuel line from the petcock. Maybe this is causing the fuel to constantly be drawn into the carb?
Any input is appreciated!

Are off road motorcycle helmets legal on road in Australia?

I was hoping to purchase a Fox racing V4 helmet for a honda crf250l which I'm planning on using mostly for on road communting. I'm new to motorcycles in general and could not find any useful information regarding legal use of off road helmets in Australia (NSW).
