I can not get smooth control of my bike on corners. I know a lot of it has to do with the amount of speed I have going into it, and I need to work on feeling and knowing how fast or how slow I should go on corners. But, my problem of my front end being squirly is still persisting, I come out of corners off of my intended line all the time and its caused by under-steering or over-steering. I keep my inside pedal up and sort of aim my knee towards the direction I want to go. When Im going down a hill I stand up but on the flats I stay seeted. Should I stand up on corners as well? Or do I really need to just practice more to get a hold on it?
