Pyramid Plastic; Fenda Extenda
(I write this in english because my german is not that good..)
The "Fenda Extanda" works very well. I have fitted my CB1300SA with such an extender/kotflügelverlängerung - it looks like it is a factory part and the cooler and also the stearing head bearing is well protected aginst dirt (and small stones)
After long stretches of gravel road in Norway and Sweden this summer, there were no damage when I came back home- but the oil filter looked sandblasted..
PS: If you have got some small dents in the delicate "finns" on the cooler, an old trick is to trim a match or a toth-pick and then use this a an alignment tool from the other side(!) of the radiator (through the radiator finns- if you try it from the damage side you will often make it look worse)
