Hmmm.
I do 4 x 115 miles a week going to work and back - I'm only 5'10", but short-arse legs and long back, and the buffeting is driving me crazy. Even with earplugs it is painful.
I had decided to get a pair of tobinators, but a few days ago came across a post in adventure rider that just said "no screen = no buffeting". Well, the screen is on the garage shelf. (Bike looks much less pretty without it, if you can see pretty in a GS to start with, that is). I'll let you know if it is better or worse after the 230 mile round trip tomorrow.
There ought to be a 'loan' pair of tobers going round the forum for tests
