The flick is different from countersteering. Bryan Lopes describes it well. Capricorn, When entering a left hand turn. Do you push your left hand down and pull right hand up? If you do you are creating forces and tension on the bar which takes away from steering efficiency. If you lean the bike by just falling over to the inside then you not going to be balanced with your weight on the outside pedal. You probably don't realise it but if you are using good technique in leaning the bike over while keeping your body fairly upright, then you most likely are countersteering. It's such a slight movement. Upon entering the lh corner, your body is starting to lean slightly to the left. You turn the bars imperceptibly to the right and you relax your hands and arms and allow the bars to 'flop' into a position where you are not fighting the bars. At the same time your weight is fully transferred onto the outside pedal and you lean the bike down while standing upright (saddle dropped). Throughout this process you are looking through the corner so that your head, shoulders, hips, knees, feet point towards the apex/exit. It takes a lot of practise to get everything working together in harmony but when you do it's all smiles.
