Why couldn't a wider shield fit the same way as the one you have?
The edge would bang into the tupperware?
Wider at the bottom might bump into the cat-catchers at full lock.
Wider at the top might be nice, especially in the rain, but wimpy
handlebar mounts might not be able to resist the wind if you put
up too big of a sail... the OEM mounts weren't wimpy, but the
windshield was awful and none of that comes anywhere near
close to fitting on my bike now.
Real fork mounts would take a lot of doing what with all the plastic
around the upper fork legs, and stuff there would be tucked right into
the cat-catchers...
This little shield has very little buffeting (I only went around 60 or so)
and the air shoots around me to each side, and hits me in the
upper helmet... I can tilt it up a little more and maybe still see over it,
I'm going to try that. I really enjoyed my fully sighted test ride on my
newly comfortable hot rod this afternoon
