I made something up using polycarbonate, it proved to be VERY tough, even surviving being dragged down the road in a big sliding crash into the back of a van. It cost about £15 for the piece (including practice bits).

In the end I took it off as I hadn't got the angle quite right and while it protected my body from the slipstream it kind of pushed the wind into the top of my head.

I basically cut it to shape using a jigsaw and the bent a crease in it to give it stiffness (although I'm not sure it needed it) by gentle application of heat using a heat gun. I got a straight line by clamping wood either side of the bend with g-clamps to hold it straight. The poly was 5mm thick, reckon 4mm might have been better. I basically just bolted it to the original plastic headlamp surround which seemd perfectly strong enough, with rubber spacers to increase the angle.

I am, however, planning to make another. It will be much steepr, say 10 degress or so off vertical, wider and have a little lip at the top to help kick the slipstream over the head. I'm also planning to fold it round the headlamp a bit in a sort of rally screen stylee. I'll do a mock up first in cardboard.

For pix of the original 'in action' click on my scotland - nepal blog below. There are several pix of the bike with it on. In fact there's a link to 'the bike' which, if memory serves, shows the screen.
