Just to reignite the thread, I though I was okay at slow speed riding. I attended a local IAM slow riding course yesterday morning at an empty car park in whiteley and spent the morning attempting to ride around various coned-off routes in groups of 6. I was particularly amazed at how poor I was with riding off then applying full lock and coming to a stop again. At the end of the morning practice I was a much smoother and more controlled rider and I had a lot of fun practicing my slow control.
I would highly recommend such a course to anyone to brush up on their skills.
