I'm in the process of cutting out a polycarbonate extension to mount at the top of my Roadster screen. My experiments with lowers have produced useful data, but the bottom line is that the screen is just too short. I was thinking the original manufacturer might have something else that would fit this hardware, and I suspect the OEM is National Cycle. I've come to that conclusion for two reasons. First, NC has all the parts to mount their Switchblade series windscreens on late model Triumphs, but they won't sell them as a kit. I don't know any reason they would do this, unless they've signed a non-compete with Triumph. Second, I recently measured several of the hardware pieces on the Roadster and discovered that everything is SAE sized and threaded. That, plus the general fit and finish of the windshield, convinces me it's made in the U.S. So, has anyone here ever compared the Roadster screen to the various models from National Cycle? Is it possible this screen has the same hole pattern as another model in their line? I sure would like to buy a taller, straight-sided replacement screen (no running light cutouts) that actually works at highway speeds.
EDIT: Just want to add that the straps on the National Cycle "Dakota 4.5" screens appear to be identical to the Roadster in online photos. If the Dakota screen will fit our mounting hardware, it would be a big improvement in coverage. Does anyone know?
EDIT Again:
Here's a comparison:
