changing the final drive gear ratio on the GL1800

Just for the sake of discussion lets say I could change the final drive gear ratio on the gl1800 to drop interstate type driving by 500 rpm's. I'm using 500 as thats pretty much how much the rpm's change from 4th to 5th and I like some others I know would really like a 6th gear type rpm at interstate speeds. What do you think the average rider would be willing to part with to have that kind of mod done? It would involve removing your final drive (not difficult at all) sending it in having a new gear set installed and of course properly set up and you re-installing it. I don't want to get into whats it made out of or is it reliable or any other type of tangent issues. Lets just keep it simple. I ask this question to find out if it would be worth going thru all the monkey motion a set of properly designed gears would cost to do this...I am considering it obviously or would not throw it out there. My question is aimed at those that feel as I do that the rpm's could come down for interstate type speeds so mpg doesnt take as much of a hit. Thanks fellow riders

So many older posts are shooting this down because it doesn’t increase the mpg much. For me in my area you can’t blend with hiway traffic these days without pushing 80mph. Also the 1st gear is so touchy, but we just get used to it. Not good on such a big bike. When doing a uturn, that gets a lot easier on a stock wing in second gear, one winger even in 3rd. I want this mod for the drivability not fuel economy. Mine shipped yesterday, and from the emails its been a pain to get oe parts. Hell, I can’t even get parts for my pool right now. Guessing these might become unattainable soon, I had a 6 month wait because of honda, not Henry. Im sure he has other endeavors that he can make money on especially when he can’t get parts. I feel lucky.

Welcome to the forum.

There are more recent threads regarding the Henry final drive. You should check those. I do not know that Mr. Henry checks this site so you should contact him through his own web site:
