Otherwise get a fiberglass black gel coated custom XL fly from the UK like Steve
@1olbull and I have fitted at the moment. I added an Aussie custom laser cut stainless steel strip with Southern Cross to mine and like Steve find it perfect for long distances with our somewhat larger frames.
XL fly available from Rocke's Patches UK:

or on FaceBook Triumph Rocket 3 For sale Jason Dunne Fiberman:

Also the French Bullster??? screens that I think
@albertaduke and a few others like
@barbagris have tried or use. They will chime in. Those screens are available world wide from dealers.
If you want to be different you can use also dual headlight flyscreens from Triumph streetfighters with a customised bracket set up.
I have a couple in the shed including a carbon fiber one and heaps of Triumph R3 fork clamp mounts and different screen mounts, brackets and aluminum spars to try some day.
