I'd start practicing using your motorcycle riding it around; commuting, just generally using the motorcycle and you know... obeying all the laws the MTO would want you to obey. Other good things to do while on the motorcycle since you had your M1 are the basic concepts of riding a bike that you should know, should have figured out in the handbook and the M1 course, and that you should have been doing since you started riding a motorbike.. Things like basic lane positioning.
Hope my sarcasm shines through.
These threads always make me laugh.. SOOOoooo you need to practice specific things to get your M, but after that.. and for the rest of your driving/riding carreer it'll be a big 'F*-it' and you'll just go about riding however you did so before you did your M test where you needed to refresh/practice the things you should be doing all along.. lol...
Maybe don't get your M. Safer for you and everyone else.
