Kevin (Spin Doctor on Visordown) over at Survival Skills has put up an excellent post on sorting out your lines on the road. I like this for a couple of reasons, the first being that every now and again I get a bit ragged in my cornering and feel really ackward, and also that he puts his finger on the building blocks to sort it out.
Motorcycles are relatively narrow compared to the amount of road width needed by cars, and there are more options for positioning. They also carry less grip, so the options for getting out of cornering problems can be less if you aren't so sure of your machine and skills.
I recommend a read of that post if you are a motorcylist.
