Hi Mike,
Well as far as I recall mate ...
The screens on Bike's No2 & No3 are both the Yamaha 'Flip Up' screen .. slightly smaller than standard issue and as you see the top couple of inches 'flip up' and forward away from the rider.
If it's No1 bike you are looking at .. it's a Tinted Double Bubble from Skidmarx .. that's my first bet .. but the truth is I'm not 100% about it.
I think Mike GTX (Falcon 269) may have had the same screen once .. he may be able to confirm?
Hope that helps .. Stay Safe. Polar Bear.
