    Front fender droop 82-83 GS1100E

    I am painting a 82 GS1100E. Every 82-83 GD1100E front fender I have seems to have a deformation from age. The straps in the front of the fender under the triangle cutout seem to bulge outward from the weight of the front fender. I looked at all 5 I have and they all have a varying degree from to significant to a slight slight outward bulge. Is a new fender the only cure, and are they available. I was thinking about epoxying some thin metal straps inside the fender to eliminate the bulge. Has anyone dealt with this.

      I suspect it is wind loads that are deforming the fender but I agree that they all seem to have it. Mine certainly does. You might have a hard time getting metal strips to stay glued to the fender but I would say that is worth a shot. Make sure you extend them up into the curved portion of the top of the fender a bit to prevent a sudden stiffness change that might cause cracking issues.

      This is the best one I could find from when I was repainting things. It is the two slender pieces that extend forward that bow and you can see a bit of it in this shot. Ignore the grotty paint, there were experiments in progress and that is not how it finished.

        I have one of those front fenders and wondered why it's made out of soft material...other than metal.

        Interesting topic.

        my opinion shouldn't be taken as gospel or in any way that would lead you to believe otherwise (30Sep2021)

          I have the 1100 fender on the 850, because it fitted perfectly and there's a humungous brace built-in under it. Does the job really well, to the point I don't think I need to bother putting an additional brace on.
