Interesting windshield ..

This windshield is designed for recumbent bicycles, but I'm wondering if it could possibly work on a motorcycle, particularly if it was tilted forward a bit more..

Just make sure that there is enough clearence for the front tire both in width and fork travel. There are similar versions for scooters over in Asia that usually include a frame that goes over the "cockpit" and attaches similar to a sissy bar.
That would help prevent the top of the windscreen from deflecting down toward the driver's face at highway speeds... gotta find a pic of that scooter solution.

Here is one on a Piaggio



(BTW: I meant clearance not clearence)

Good catch.. Remarkably similar really.

Now if you were to incorporate a tapered tail to help close the airflow at the rear you could really improve efficiency.. Make the tail a storage bin and kill two birds with one stone..
