This is my 1966 Royal Enfield Revelation on a 900 mile tour from John O Groats to Bristol. It is upgraded to a 5 speed wide range hub and drum brakes. It surprised me how well this bike performed. The load is so low that it doesn't affect the handling of the bike at all, its only noticeable on hills that you have the extra load. I used a 17T rear sprocket on hilly days and a 14T sprocket on flat days. It might be nice to have more gears but the range provided by the XRD5(w) hub was good.
