Recommend sports bike for 5 foot 3 inch tall person?

I will be 16 years of age soon, and currently race with a crf100 (although it is much too small at this point haha) and out and about I drive a crf230l with no trouble. I'm 5'3" and weigh 135lbs. I'm looking into getting a sports bike, and am considering a ninja 300, or a honda cb500f. The ninja 300 seems ideal, but I worry it is too small, and won't do much more than 130kmph. What would you recommend?

What type of dirt bike should I get?

I'm 5'11 and 150 lbs. I'm an intermediate rider who's looking for a bike that has dual sport capabilities, any suggestions? My uncle offered to sell me his 2003 Honda crf 230 that's in great condition for 1000 or less and I'd need to buy a conversion kit for it, good idea or no

Want to upgrade to a bigger cruiser?

This is the second season I haven't had a motorcycle and I can't take it anymore! I previously had two honda shadow 750's and they were great bikes, but I want something with more oomph. I'm pretty open to any manufacturer. There are a few things that I'm looking for in a bike.

Low seat height. I'm right under 5 7".
Somewhat light bike. 550-650 ish pounds
Less than $5000.

Need a honest opinion on new honda cb unicorn?

I'm thinking of buying a new bike and this is my first bike. But i'm confused which one should i buy and by the way i'm looking for a 150 cc bike which should have a good fuel efficiency. I thought of buying unicorn but so many people said the newly launched unicorn ie, CBunicorn has so many cons like alignment, chain loose etc. So i need a honest opinion on new cb unicorn. Advance thanks for the reply…
