I’m 5’11” and I’m on my third replacement screen in the quest to find a good solution to the head bobble. Wearing a TourX, the best screen so far has been an MRA sports screen which is basically the shortest on offer. I’ve now got a medium Touratech rally style screen fitted, but I’ve already cut the top upstand portion off it to see if that helps. It was fine up to 60, but beyond that, the vibration started to make itself noticable again. I haven’t been out on the bike since altering the TT screen.
It seems the ultimate solution is to fit the wind blocker thing to the petrol tank sold by Rugged Roads or similar items by others, but it looks a tad ugly. It beats me how Honda have let this ‘flaw’ through the design process. If they’d added the plastic shield fitted to the bottom yoke like KTM, BM and other manufacturers have done, it’d be a much nicer bike to ride.
