These brackets are designed to replace the black plastic ring on the key cylinder of a 2001-2006 Honda CBR600 F4I (Non-HISS). It requires removal of the two screws, and then simply remove and replace the ring with this one, reusing the screws.

These brackets are 3D printed from a very durable, UV resistant PETG plastic.  They are also available in Carbon Fiber Reinforced PETG Plastic (only one color available - Charcoal Gray).

Disclaimer: No 3D printed part is ever flawless. It is guaranteed to fit perfectly, but not guaranteed to be without 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.
