my advice is to ride it normally at speeds up to 45mph (actual) its first 300km, then ride it normally, period. you don't have to baby these engines too much during break in, in my estimation. the owners manual also calls for an oil change at 300km. my dealer said it didn't need one then, and it didn't have one. didn't seem to hurt anything. but i also think my dealer rides the scoots around for several miles, then changes the oil before sale
i have around 760 miles on mine now and have rode it normally from 300km's on. as another posted, i do not maintain one speed for too long, however. and i don't go WOT for extended periods. i let it warm up well before i get going (when you hear the idle drop you're good to go) and take it easy for the first several minutes. then i ride it like i stole it. just had its first service and its all good
don't jump on the throttle from a dead stop, no extended cruising at one speed, vary the rpms while riding, and no extended WOT for the first 2000km's or so
manufacturer suggestions for max speed at break in is very conservative and outdated. just ride it as you need to at any given time, but bring it back down if you really have to hustle down the road sometimes
