Rizoma clearly makes the the most beautiful billet accessories for today's modern sportbike.  This multi adjustable and functional kit for the Aprilia RSV4 is no exception and includes:

• License Plate Supports (for different size plates)
• Support lights
• Indicator brackets
• Reflector kit

Get rid of the huge undertail on the Aprilia RSV4 and tidy up your rear with this very adjustable kit. Includes hangers for stock or after market turn signals.

(below images show with Euro plate, US plates are the smaller ones). Honestly you cannot get rid of the license plate and it is often illegal to place them anywhere else but at the back end of the bike so why not make the license plate locator a design element that enhances the looks of your bike instead? These Rizomas will fit the bill.

Some Loctite blue is recommended on the screws.
