Custom CF rear (longer) hugger

I'm working with a local carbon fiber shop to design and produce as functional as possible rear fender for wet conditions. This will be plug and play. I don't expect/ keep my hopes high that this will be the comprehensive end all to the rooster tail but I'd like to have something that will decrease it significantly if only something certainly better than the existing OEM/ aftermarket short fenders. I bought the 939SS for it's multi-functionality, daily commuter, distance tourer, and occasional track days. For the first two purposes only short sport fenders exist which does diddly squat with wet roads.

We are in the final design phase prior to plug making and then first prototype. The fender shown here does flare out a bit at the edges if you can't quite tell. I was aiming for the rear hugger shown in the last photo. If anyone knows of a video of a bike riding through rain which captures rain spray from the side, please let me know. I can't find one! I acknowledge I'm working on this somewhat blindly, trying to maximize rear wheel coverage. Another detail, there will be a one inch clearance at the apex of the tire to hugger. I'm aiming more for function than form.

Feel free to pan it, like it, but I'd appreciate any technical advice.

I can't provide any technical advice, but I agree with the other responses that this looks very promising.


I know it might be heresy among the Ducati acolytes, but I would not have a problem if this was made of a quality plastic, as compared to carbon fiber, to keep cost down.


Looks great and well thought out!

Hi,
please remember that the right side of the hugger should be open to be able to remove the wheel

Ducati was my first love and it will be my last.
