I (try*) to keep track of the maintenance which I do on my 2013 LIKE200i (made in May 2012 if I recall correctly) in the back of the owner's manual....which has been mended a few times with tape.
A few yrs ago a member copied his blank page and emailed it to me - I reprinted it again today and taped it in the manual.

I never fail to
do the maint.....just sometimes too whipped when getting up from the garage floor to remember the maint. log!...which I keep in a sealed plastic bag in the scooter, along with ins. papers, registration, $20 bill, & pen and paper for the details of the crash!
