Or did they maybe make an earlier set that only mounted with tape. Which would be useless. The set shown in the picture depicts the one I have, which requires some tapping of the fender mounting holes to bring them all the way through?
Come on Larry. They attach with two bolts to the top fender mounts, and two thread nuts to the bottom.The tape is just for vibration on the sides.
I don't remember any mounting holes on the original Bushtec version. I looked in my parts stash, and I don't seem to have them anymore, so I can't say for certain. It did not look like the Show Chrome version pictured above.
I was never convinced that fender extenders were causing the problem, but I don't have a theory that can prove otherwise. I have had an extender on my bike since it was nearly new, and 15 years later the fender is still fine. Folks without extenders were getting cracks too, and the problem never turned out to be as prevalent as feared. I never was very good at playing follow the leader, so I guess I just never bothered to worry about the whole debacle.
the rear half of my front fender broke at 250,000 miles, that was the only warranty claim Honda ever denied on me, they denied it simply because I had a show chrome fender extension not a Honda extension. I repaired the fender with some $50 3m epoxy and it's still holding fine. Despite what the Honda rep said I say the reason the fender broke was because the anti dive valve was stuck. I disabled the anti dive valve and removed the fender extension, the only time I miss the extension is when I ride on gravel roads and sand gets stuck in the radio buttons. If your bike is under warranty I would be very reluctant to install a aftermarket fender extension or the braces because if it does break Honda will use that excuse to deny your claim.
I don't think you need the braces, I have a fenda extenda on my bike since 2005 with no problems.
They are a light piece of ABS plastic compared the heavier metal from other venders.
No holes needed, ABS cement them to the fender.
