I've got Palmer's set at full height & upright tilt + Ermax screen but never tried them with a standard screen, it'll be interesting to hear your findings. I'm 6'2" and wear a Shoei Air GT, my combo is great improvement from standard but not perfect by any means. Having said that I can comfortably ride at around 70mph with the visor up which is nice in recent weather.
I've wonder if adding one of the small adjustable extenders to the top would make it even better, anyone tried/have thoughts on them?

When I get to it I'll post back to this thread.

I've had a Givi adjustabe screen for a few years. When I purchased it new there was a speed restriction ( 110kph I think ) fully raised. After doing a fair amount of touring I worked out to lower the screen @ faster speeds anyway. Never lost the screen fully raised at speeds up to 170kph but the wind buffeting was a bad issiue so worked out to lower it half way down which was a happy median between screen & helmet. But having said all that, mostly now ( not touring ) I remove the top all together. Personally I think with the weight, height & ergo's of the Crossrunner renders them not suitable for large screens like the big cruisers I've had in the past.

Presumably the OEM screen is designed to withstand the maximum speed of the bike (as you might live in Germany!); I find it hard to believe that 140mph (?) windblast on the standard screen would put less stress on the mounts than a slightly larger screen at say 70-80mph . . . smells like the GIVI screen wasn't up to it.

probably tested to max 70mph.
sure no one ever speeds . ,,,
right :015:

lessons learned. thats what forums are for.  :020:

if ya got a dealer to fit it on a bike new out of the showroom, i wonder if they would be fed up or emailing and complaining for a fix? the slide out holes downwards on the honda mounting, shouldnt even exist. its ¾ the problem.
if i cared about being judged by a stranger, i'd be religious.

Other bike manufacturers opt for simple round holes to house the rubber screen-mounting Wellnuts.  However, Honda have designed a "slotted keyhole" type of hole. This enables the screen to be removed by slackening (not entirely removing) the fixing screws and then sliding everything downwards out of the "keyhole". The big drawback here is that the incomplete 'circle' distorts the Wellnuts, which eventually squirm out of the slotted hole, thus negating any notional advantage that the keyhole system might seem to offer.

My fix for this has been to fit some longer rubber Rawlnuts and slip washers on to the back before tightening the screws. These longer Rawlnuts then expand into a much bigger and more secure blobby bit which cannot squirm past the washer. The washer presents a round hole to the rubber nut and bridges the keyhole slot of the original Honda brackets. It works!  :152:

Here are some photos. In time I may swap the screws for prettier hex heads but they are M5 thread, just the same as the original.











So far the whole screen installation has remained secure and steady at all speeds  :164:

Something like this should do the trick  :-

Who in their right mind would design a vehicle that falls over when it stops?

I did a long ride today over mixed fast roads plus some very bumpy back lanes. The screen is still on!  Nothing moved. The main saviour is the washers, to span the Honda keyhole slots.
