I like to keep the numbers of questions on our current Scooter Answers category pages down to a usable minimum. Too many questions to scan through can be overwhelming. So I've created these archive pages so that you can still find answers to almost any scooter question through search, but the most current (last month's) questions will be easier to scan through and answer or just learn from.

So, this archived scooter questions page is about strange sounds in a scooter. If you can't find what you want here, feel free to explore the other archived topics listed here. And actually, the easiest way to find anything in our database of questions and answers is probably to use our site search box:
