^ Similar sort of bike to what I have, though mines older!
I'd say you just need to find some tracks and have a go. Learn by doing
You may already be doing this but I always used to find it helpful to practice tricks a bit too - bunnyhopping, for example. I was just doing this outside my house and it allows you to do so much more on the track! Not that I ever went very extreme, but I had some fun
All this talk is motivating me to get my bike out of the shed, maybe tomorrow since Im about to start work until after dark!
