New Rider- Advice?

Hello! I've wanted a bike for some time, but in my family they're not really accepted (esp since I'm the little sister!). I've decided that at 24, why not?! So, I'm doing my research as I have been for some time. I'm really just wanting to ride just to ride. Although, I must say speed appeals to me, when I can handle it of course!
I've read the stickies, and have been researching for some time. I'm thinking of going for a Ninja. I've heard lots of good things. I have minimal xperience in the form of driving a couple of guy friend's bikes around the block. Other than that I'm seriously inexperienced. Already got my safety gear picked out, and am about to enroll in the safety course, and of course I'm reading a lot (no substitute for experience I know!)

Any advice, caveats, words of wisdom for me?
Thanks in advance!  

KiloTango -- Sounds like you are level-headed and are taking the right approach.  I don't have much advice to offer in terms of preparation.  You know the risks, you're enrolling in the MSF course and you're reading about the techniques and warnings from other riders.  Props on the gear as well - I still wear all my gear, all the time.

As far as bikes, Kawasaki isn't bad as they have several good models that work for starter bikes.  Look into the Ninja 250 and Ninja 500.  Both are good starter bikes without too much power to handle.  Consider a Suzuki SV650 as well - that's another fine machine for starters.  Also, unless you have a fair amount of cash at your disposable, I would consider trying to pick up a used bike.  Insurance prices aren't pretty on new bikes and if you do put the bike down, replacing that plastic won't be as expensive.

When you get to riding, start slow and in sparcly populated areas.  Make sure you are comfortable with your bike and how to handle the bike before you move up to higher speed limits and higher traffic.  Don't forget to practice panic stops!!  I GUARANTEE that you will have to use that skill.  Practicing it will come in handy.

The best advice I can offer...Stay in your comfort zone.  Don't get a big head and get into a situation you aren't 100% comfortable with.  Leave your ego at the door and ride your own ride.  If you do that, you should be fine.  Oh, and always assume that car in the driveway or that joker with his left turn signal on will cut in front of you!  You won't be easily seen, so just be prepared and assume the other driver will do something dumb.

Best of luck and welcome to the riding community.  You're going to love it!
