I have been riding my recently purchased 07 America. When I'm on the highway doing 65-70 I find myself sorta wishing I had a 6th gear. Although I have no tach it seems to me the rpm's are a little on the high side. A friend of mine (also a triumph owner) told me he thought he read something once about changing out the front gear on these bikes to bring the rpm's down a bit at high speeds. Does anyone have any experience with this or any other information about this type of modification?
