I like your idea.
I like free speed too; that's one reason that I like your idea.
Like Mr. B. Pedals, I installed wheel covers on my rear wheel.
The free speed boost is welcome, but the extra unexpected bonus,
for me on my bike, was the added stability.
I carefully cut and fitted my first wheel discs myself.
Cardboard is free.
As a retired motorcycle test rider, for a fairing manufacturer, I'd rather
not have to deal with front fairings mounted on a monotrack vehicle.
It'd be too much like work.
But that's just me!
Good luck!
