Welcome to the site :cool:
Be sure and go to your User CP and update information relating to your location, type of riding, etc. After that grab a spot on the couch and tell us a bit about yourself.
Check out the
What Bike Do I Get... ? forum for great information on what dirtbikes might suit your needs and desires. There is a great group of folks that hang out in there always willing to help a newbie to the sport.
Again, welcome to the site and shout if you have any questions!
