I have a 84 softail with 4 speed stock trans. Would like to cruise at lower rpm at higher speeds on freeway ect. Any suggestions about rear sprocket or trans ideas. Has chain drive-thanks

 

I am very interested in your question as well. I have grown accustomed to highway driving in my car and can only imagine i will be doing some on the bike. I thought my only option was a new 6 speed tranny.

 

drop the rear sprocket to a 48Tcut a couple is links out and hit the hiwaystock is 51T the front should be a 23T

 

Better yet. Do like me. 25 tooth at the trans output and 47 on the rear wheel. Works wonders for me.
