04-05 Honda CBR 600 F4i Fiberglass F13 Installation Guide
Please test install this undertail BEFORE painting it. Even though we’ve tested our parts on designated bike models, it still may need slight modification to fit properly with other aftermarket parts.
Installation:
We highly recommend having a professional install this undertail. A dremel tool or similar is what we found the best to cut plastics.
1) Place bike on a rear wheel center stand.
2) Remove passenger seat and hardware which secure stock undertail section
3) Unplug the harness that connects tail light and remove the stock undertail.
4) Position Bestem undertail close to the bike and determine the amount of plastic needs to be cut out. Use a dremel tool to carefully trim off plastics (glove boxes etc). This is the most time consuming part of the installation but your patience will be paid off.
5) Once the new undertail is slide in, determine holes need to be drilled (only on certain models). Reuse the hardware for the stock undertail to secure the new undertail.
6) The wiring color codes from two round tail lights are
Black Wire – Ground, connects to Ground wire.
Red Wire – Brake Light, connects to brake light.
Blue Wire – Running Light, connect directly to the running light.
Orange Wire – Turn Signal, connect them to your L/R turn signal wires
We highly suggest you solder the connections and use heat shrink wrap to seal the connections.
Test your lights before going out for a ride, also make sure your new undertail is securely installed on the bike. Now it’s time to go out for a spin!
