Just to say....I tried the Ermax offering.
It is hopeless! More wind-noise and buffeting than Honda original. Also badly finished with cheap spray paint used to provide shading. AVOID!
But I am still looking for the solution.....THe Givi Aerflow doesn't fit the latest model, sadly!
Oh, and on Huggers...the Pyramid plastics version fits alright and looks nice but doesn't do anything useful! It is not tall enough or wide enough.
So useless screen and pointless hugger both available!
