What up-keep are you referring to? The chrome tank is the only bit that requires attention on regular basis. Its nothing that autosol wouldn't fix!
As for the rest of the bike, it is no different maintenance wise to the new model. I am just curious, maybe I am missing something?
Many believe the chrome tanks require more cleaning/maintenance. I am not sure I agree and find it pretty easy to look really good. I had a polished aluminum tank on my v11 sport. That needed a bit more than the chrome but not much. Just my experience.
