First Bike

[Tmann]

I'm wanting to get into motocross riding and trying to find the right bike for me I have very little experience on a bike and trying to pick the best for me. I'm 18 about 5'9 and 150 pounds I have been looking at the Honda 150cc and Honda 250cc and need a second opinion on which one to purchase or if you think another bike would be good any help will be appreciated.

definitely start out on a 125.
when you get good on one you can also go as fast as most 250's.
