THE BEST SEAT I have ever sat on for long distance is the Road Zeppelin. I put this on my FLHRSEI2 and have never regreted it.
It will tell you in the H-D Catalog of parts that this seat will not fit. It will! I have had it on mine for over two years. Last long ride I took, was to Milwaukee from San Jose, Ca 5938 miles round trip. Wife flew to Chicago & met me, BUT rode the 3,000 back through Colorado. Best adjustable seat I have ever had. ONLY MODIFICATION: The seat hold-down bracket won't work. Either make your own, or??? Needs the centerline of the mount to fender hole increased by one inch.
Hope this helps. I have had Corbin, etc. Nothing comes close to this seat! Not a lover of H-D, just that this IS the best game in town... [smiley=banana.gif]
