This is by far the easiest and best thing you can do to improve the looks of an Aprilia Mille. License plate brackets are easily made or bought for $40. Everyone knows what I'm talking about so let's dive in.
Before...
Time to chop off those ugly ears! Don't bother using a Dremel or high speed blade of some sort. That's way too aggressive and the blade will heat up and cause problems with the plastic. Just grab a simple Japanese saw from a hardware store like OSH or Lowe's. They are 10-20 bucks and you will wonder how you got along without one! They are seriously one of the best tools for custom work around the house and a MUST HAVE for working with plastic. They cut through plastic so easy it's amazing.
