I purchased several aftermarket screens in the vain attempt to reduce windnoise whilst out riding my vfr. For the book I’m 5’11” or 1.8m in new money. Helmet used either Schuberth E1 or Arai chaser. Both fit well. Wear custom fitted earplugs. Have 1/2” risers. I thought it best to leave top box on to give you a good idea on the height of the screen Overall conclusion of trying 3 different screens in 4 configurations the Givi and standard work best for me. The 3rd screen not pictured was a puig touring screen with the adjustable blade. It was removed after 250 miles because above 70 mph in any configuration it caused so much turbulence that my head was shaking to the extent I was getting double vision. Top pic Givi touring great screen saves you most of the windblast although head is still in the airstream and noisy Middle power bronze double bubble good screen better wind protection than normal screen still getting Windblast from top of shoulders. Bottom std screen wind blast from about nipple level up. Sitting up higher still in blast but drops the windnoise down dramatically. Holes in screen are where I had fitted the adjustable screen. Verdict about as much use as a chocolate fire guard.
