I am going with Stig on this one. If it is new and you have a noise you are worried about then take it to the dealer. you have a warrenty they should be able to check it at no charge and fix it or tell you it's ok and why.
If they try to charge you then look at checking it out yourself, but only after they check it. Because even if it is a problem from factory on your scooter once they notice you opened it then they will claim you did it and never fix it under warrenty.
