I have been riding since 08 and I still can't 540.
Its not a basic trick like almost everyone else said, learn the basics first. Tail whips and bar spins are not the only tricks around.
When did anyone say you weren't good enough to post on here? All we said is you have no room to make fun of anyone when you are so new to the sport.
Save the shit talking for people that actually know what is going on in the sport.
