I find the tri glide seat to be low causing me to feel my knees are in my chest. The sound system seems to preclude placing my legs forward; foot pegs etc. Does Harley facilitate any particular ergonomic adjustments. I'm 6' with 32 in inseam; so relatively avg. I'd think.
Check with your dealer about demo seats that you could try. Floor board extenders (DK Customs) will help also by moving your feet out an inch. Highway pegs will help stretch out while cruising.
