Here are a couple before and aft pics of a friend's bike with the fender mod. This first prototype was made out of 6061-T6 aircraft grade alluminum. Plenty strong enough but I still plan to make the sets with either Titanium or 316 Sstl mainly only because some people may not trust the aluminum although it is plenty strong. The upper offsetting brackets that you see were modeled up in solidworks and stress analyzed by engineering. I want people to be confident they could give big Aunt Bertha a ride down a potholed street and not worry about her busting her ass and ending up on the road. lol So the brackets are damn strong. I plan on using only good grade 8 hardware with it too.
If you look carefully you can see the offset spacers that go between the fender and the frame. On the idea, I tried my best to make this a fairly simple completely bolt on option, with no cutting or prodding required to your stock equipment, so that most anyone could manage it. That way if you ever want to reverse it to sell the bike or whatever, it will be super easy.
I don't know how these pics will turn out clear enough. It was quite a fiasco of hoops just to get these on here.
