whats the diffrence
what is the diffrence between a heritage trans and a road king trans cause my 04 king seems to ride at a lower rpm at the 70 75 mph.. and doesnt lose speed the same way when i come of the gas it keeps the speed pretty well.. is there a diffrence in the final drive?

I doubt the transmissions are any different. The motors are different, though. You have the 88a (rubber mounted)motor in the rk, and a heritage has the 88b (counter balanced). Don't know if this would cause the rpm difference, but the engines are mounted differently.

RE: whats the diffrence
The transmissions are the same the difference is probably the final drive ratio.Those geared 3:37 are going to be much snappier out of the hole than say something geared 2:05.Find out what size your rear belt sprockets are.That is where you could make a change.
