These brackets are designed to replace the black plastic ring on the key cylinder of a 1999-2000 CBR600 F4 and 2001-2006 CBR600 F4i. It requires removal of two JIS (Japanese Industrial Standard) screws, and then simply remove and replace the ring with this one, reusing the screws.

There is a wide variety of USB chargers (not included) that will fit this bracket. There are also voltmeters (pictured) that fit. For links to the chargers/voltmeters I use, please send me a message and i'll be happy to share them.

These brackets are 3D printed from a durable Carbon Fiber Reinforced PETG plastic.  The material prints beautifully, and has kind of a matte finish.  The photos of the bracket on this listing that show it uninstalled are photos of the carbon material.  The photos of it installed are photos of the same bracket, but made in regular PETG plastic (not carbon reinforced).

Disclaimer: No 3D printed part is ever flawless. It is guaranteed to fit perfectly, but not guaranteed to be without very minor cosmetic defects. For examples, please examine the photos carefully. That part was installed right off the printer and is representative of a typical part.  Please know that I am a quality assurance specialist by trade, and a bit of a perfectionist.  I will not send you a part that I wouldn't install on my own bike.
