I would highly recomend taking the class... it will teach you things that you need to SURVIE driving on the street.
the test is not that bad... you go a short distance one way showing that you can up shift, down shift and brake smoothly. then you have to be able to drive in a tight circle( between two lines, this will be hard with a road king) I beleave there is a salom of cones as well. Its been 7-8 years since I took the test. I no longer ride on the street.
