Default Street Bob rear fender cracking issue : solutions

There are two threads running on this issue :

this one

and

and this one
  • Some are proposing removing the sparto tail light
  • Others suggest moving the license plate to a side bracket
  • Others just replace or repair the fender

I would like to keep a dedicated running / brake light on the rear fender AND have the brake / turn signals continue to do their work. So I'd like to find a lighter weight tail light.

I'm not happy about the prospects of moving the license plate. I would probably rack my shins on a horizontal side mount.. ad as I travel state to state quite a lot, and don't want the tickets associated with a vertical mount.

What are others doing? Any other options to be explored?

Can we reinforce the fender?
Find a better way to attach the tail light / license plate bracket?

What else?

It happened to me as well and I'm just waiting on my new fender that HD is replacing under warranty. I doesn't happen to all of them so I'm going to keep it as is this time but if it happens again then I will try something else.

I'm going to look at some method of vibration isolation. Maybe a thin sheet of rubber, cut to fit. I will post something when I do it.

+1 on vibration isolation. That should do it. OR another thought: Pull the fender and reinforce with fiberglass on the inside before it cracks. I know that really sucks to have to do that to a new fender but adding material should help.

I want to know if there are other taillights out there that would fit. I've thought about ordering an old style sparto and trying to come up with something.

none of my bizness, but it would seem the root problem is a defective fender, not the light or plate. if it won't support those without breaking, good luck putting a passenger or other cargo back there...

I agree... I've had my '09 for about 2 1/2 yrs now with 13.4K miles (yea, I know, I'm not riding it as much as I should) and the rear fender is fine.

Any thoughts on putting some Dynamat back under the fender? It is a sound dampener used in car audio that reduces vibrations. Other companies have similar products. Some examples are FatMat and Second Skin. It's fairly expensive so there's also the alternative of simply using peel-and-seal roofing tape. It is similar in theory to Dynamat but significantly less expensive.

I don't know that this would fix anything but if vibrations are part of the issue, this might help.

Are those of you that are having this problem able to get the repair picked up by a dealer under warranty?

If not, I wonder if it would do any good to send a letter to HD - signed by all those who had this problem, and try and find a resolution that way?
