Remember me, the guy who was always making something for his R3T. I made and sold a lot of those wind deflectors that fit on your windshield among other things. Well, I've decided to get at it with my new R3GT. I have a Madstad windshield on my bike, but I'm getting a lot of airflow coming up from around my turn signals and front forks. I decided to experiment with a little lower project to see if I could cut some of it back. What you see here are... some fork clamps I bought, some cover plates, "my old leftover R3T lowers" that I I had laying around, and some fastening arms I fabricated out of some 1/8th X 3/4 in aluminum. The fork clamps are 58mm which is what the forks measure, but I find them to be a little bit of a tight fit. I have some 60mm's on order to see if they are a better fit. THIS IS NOT THE FINAL LOWER, but you get the idea. Lots of painting to do, a pattern that I more than likely will use (pictured), and nicer screws. A note on the pattern...I have a cutaway on the pattern for the turn signals, but I may not need it. I'm just using my old lowers for testing. I don't want to muck my bike up, but I think they will fit in pretty good. And NO, I do not want to make these for people. 🤣🤣 Those little arms are a pain to make.

UPDATE: This is not my final post, but I thought I would post some pictures of where I am at with my lowers. I have them the temporarily mounted, the protective paper is still on the plastic, all the aluminum will be painted black, I bought some really nice flat head screws for everything along with washers and locknuts. The plastic lowers may change in size and design a bit as the pieces of shatter resistant plastic was all I had and not quite the size I wanted. I had to remake two of the twisted aluminum arms because I needed opposite twists to get the lowers to swing back the same on the opposite side. I use 60mm clamps instead of 58mm and put a thin strip of rubber grip tape with adhesive on one side on the inside of the clamps to avoid scratches on the tubes. That's about it until I do my final post.

I wonder, if they fail, say, a wind will move them back forcefully, this may prevent the handlebars turn.
 
Nope, it won't happen. It's a very solid setup and secondly they will be mounted forward and in front of the turn signals not behind. Clearance is not an issue.
Then you won't have a problem taking a picture with the small shield and the turn signal being moved all the way towards the tank around the fork?
 
What hand guards do you have?
They are made by PowerBronze in the UK. I mounted mine using the original bar ends, but they I do supply all the stuff you need.

I'll post an update with pictures when I'm finished with everything mounted. Still waiting on stuff and I'm in the prototype stage for another week or two.

Cool, I have headlight covers from them. I'll check it out.

A good deal of grinding and these from my KTM went on. And a new place for the TPMS display

Looks good. It's never an easy job on doing homemade modifications. The Powerbronze hand guards work well for air flow over the tops of your hands. With my setup, I notice most of the airflow coming up from underneath the bars. I don't expect miracles, but any reduction would be nice.
