you dont need to do track days if you dont want to,but if you want to learn handle your bike better then is good choice to go least one day .it is a school with STT not just open track day .everybody who did track day get better rider.i start ride last year,and i ride with guys who ride over 10 years.i did few track days and now im more comfident and faster in corners then my friends.they come and watch us last month at midohio and they admit they cant ride like us ,and they ride for that long.
