Well the worst i got was someone said that I didnt have a ninja (even though i have all the gear and a helmet) and when they saw me in the parking lot they still didnt believe it was mine untill i got on and drove off.
otherwise its the standard "250s are to small" --Im 5'6..
and "it has no power"..your just fat
and "why didnt you get a bigger bike" --because im not worried about my cock size
