some good tips - but be wary about the counter steering one - "its a skill you must master"
you HAVE to counter steer to be able to ride a motorcycle - otherwise you wouldnt be able to go round a bend - its just that when you get to riding a bike you will do it without thinking - but its being able to consciously input countersteering to get you out of trouble is where the difficulty is
(notice that when the video says lean in a little to the turn - the riders demonstrating are actually leaning the wrong way - actually you don't need to lean at all - pushing the bar is all you will need to feel the effect)
