I have the MRA X-creen Touring Windshield for 2014 Kawasaki GTR1400 .I am 187cm tall, I find there is no back pressure with this screen, I wear a Shoei neotech helmet and I do like some air going over my head and the slots in the lower section of the MRA screen allow some air flow , balance of pressure in front and behind the screen for cooling purposes which this screen does perfectly.
I have tried a Projekt D screen with adjustable panel of the MRA X screen but there was no air flow and a vacuum behind the screen when it was right up, hence it go very hot with no air flow.
So I only use the MRA X SCREEN NOW.
Well made, fit is perfect, highly recommend this product.
The stock screen on my 2014 GTR1400 was approx. 23.5 inches from the v section at the bottom to the the.The MRA X-Creen Touring screen is 24 inches . But there is no buffeting from the MRA X SCREEN, very little flex when fully raised unlike the original screen especially when going past trucks going in the opposite direction or cross winds/headwinds.
Yes I believe the actual shield is the same, as you said the spoiler is different. As for how high I raise the screen, its either all the way up, half way or down depending on the conditions in terms of ambient temperature, weather/rain. I like some air flowing to cool as in QLD, AUSTRALIA in summer its usually 30c to 40 c temperatures and in the winter months usually 20c to 27c .I have been interested in this windscreen for a while. I see you mentioned rain. I have heard negative comments about this shield in the rain. Could I please hear your version.
With the screen right up the air flow basically hits the to of my helmet, if I duck down a few inches there is no noise or air flow to the helmet, I am 6ft 2 inches tall, so if you are shorter than that I would suggest that with the screen right up you will have very little noise or air flow to the top of your helmet.
I have ridden in rain on several occasions, not torrential rain. Whilst moving there is good protection, very little water enters the slots at the lower section of the shield. Basically the same protection as the standard screen I had fitted with a laminar lip. I would say no better or no worse than the standard screen.I thank you Mr. Smoke
