ok as far as the license on anyone under 21... when i took that msf course a few years back , they told me that state law changed the requirements on the age and now all riders must have that endorcement... no age limit to not having one , which would explain why in my class i had several people 2 times my age who have been riding since my age , being coached along side me.....their not as strict with the hogs , but with sport bikes , no mattere the age , they will site u if they pull u over and u have no also tage on ur license....my friends 28 and he just got out of court for riding with no endorcement.
