I've had no issues at all, my guard sits about an eighth of an inch off of the actual radiator face, and is obviously well perforated. I think between the location of the radiator and its exposure to air flow, coupled with the space between the radiator and the guard, as well as the perforated front that this wouldn't be an issue.
I have rode my 2016 NC700XD in 95 F up and down some twisty rides in Central Tennessee for three hours without any issues. I have the GIVI Radiator guard.
Can you make bigger, HD images, with more details, I can see better? I would like to try to make one myself.Here's the Home made one I used. The metal comes from Home depot (barbecue grill i think).
This was version 1.
V2 had plastic tubing along all edges and one more strip of plastic tubing along the center on the inside of the metal.
I figured that center strip would act as a shock absorber should a large object hit it. Never got to test that thankfully.
(hard to see, but it's held in place by zip ties at the four corners.)
Thanks!yes, I'll post the larger image when I get home. I scale them down so they won't take up as much space.
(ooops!, no I won't ! The only pictures that exist of that are on this site!... and they are the ones I used in the original post!)
How can I help otherwise?
it's metal grating (some use pieces of metal waste baskets) with plastic tubing on all four sides. Slit the plastic/vinyl tubing down one side and it will press on to the rough metal edge.. then just zip tie the tubing to the grating. You could just as easily use good quality electrical tape to cover the sharp edges, but I like the way tubing lifts the grating up off the surface of the radiator. A stone strking the grating would cause the grating to flex and absorb most of the force before it touched the radiator.
As I recall, there are metal fittings at the four corners that made attaching the thing with zip ties (again) easy.
