Hit a high speed wobble at 145mph, but saved it, deff got my attention. Any one else have this?

That happens to my brother when he's riding the bike. He's a body builder with a "thick" back that sticks above the windscreen and causes turbulence (I guess). Anyhow, a good steering damper is in order, even without that particular problem.
