Honda CBR600F4 1999 - 2000 / 04-05

Mototeck Undertail

1. Place the bike on a stand, preferably a swing arm stand.

2. Remove the front seat.

3. Remove the solo seat section or rear seat.

4. Remove the lock rivets and Allen bolts under the tail.

5. Disconnect the tail light wire and carefully remove the tail section.

6. Cut the stock signal wires as close as possible to where the signal connects to the turn signal wire.

7. FENDER TRIMMING: IMPORTANT NOTE: The following procedure involves some cutting of plastic. Use Safety Glasses for all cutting and/or grinding procedures!  The stock fender is used to retain the trunk area. You also keep the holder clips for the support  bar. The stock fender must be trimmed enough to install the Undertail section. For cutting, I recommend a Dremel Tool with a plastic cutting tip. I have used them  with very good results, but you can also use a Hack Saw blade or something similar. You basically have to cut the fender at least as high as the finished edge and also leave room for the signals. It's not critical to cut perfectly since the new Undertail covers all of the cut edges. Keep the two stock bolt connections on each side for more support.

8. Reinstall the tail section on the bike, but do not install any of the bolts.

9. Slide the Undertail up into the tail section and position the rear holes to be drilled. After drilling the holes, install the four plastic fasteners. You may have to remove the Slip-on to drill the holes on the right side.

10. Install the Allen bolts that hold down the tail section.

11. Connect the brake and signal wires. You must use the LED tail light bulbs that came with your Undertail. If the LED signal lights do not illuminate, you most likely will have to reverse your wire connections on the effected lights. Check the signal, tail and brake light operation.

12.  It suggested that you install a heavy duty Turn signal relay. In most cases, after installing LED's, the signals will flash at a very rapid rate. This relay installed in place of the stock unit will return the Turn signal flashing rate back to normal. We have these units in stock. Our Part Number is 3100610.
