Some lean into a corner, others counter-steer:
Over the years I have heard of and seen learner riders run off the road because they really didn`t know how to go around a corner.
Just finished reading a book where this chap let his mate ride his Matchless, he couldn`t turn into a bend and ran into a wire fence just above the handlebars which pushed them both off the bike, they landed on their bums unhurt. The bike was not damaged either.
I always presumed that once you could ride a bike, negotiating a corner would come naturally.
