If you're running the OEM seat... and you're over 5'10" tall... you may not like the slight amount of helmet buffeting. If you're looking for a "clear air bubble" - better do some serious research on what brand/model & size will best suit you.

IMHO... the more one needs a still bubble of air behind the fairing/windshield, the more the F6B starts looking like your run of the mill Goldwing.... IMHO, to keep the "look" and still have adequate protection, some level of compromise between style and function needs to exist for this bike.
