Bike & Frame Weight

Ever considered the fact that your skills might be lacking somewhat? You see scrawny kids hooning massively heavy bikes around all the time at any trails, d-jumps or park. Technique and muscle memory is what you need I suspect.

Yes of course my skills are lacking, I road dirt a couple of years ago but have been interested in road/street since I started uni. I'm looking for a bike to build up that technique.
