I liked the look of the all chrome gas cap that I've seen on ebay but then it doesn't have a locking feature which I don't mind having...Yeah it's a pain to keep taking the key out of the ignition but the locking feature is for tampering prevention
It states right in the auction about some issue installing them on a Rocket. Don't know if this is only an issue with the 06 models. Did you email them for the info?
The one on my 06 SE is already CHROME and has the lock.
From customer feedback we have learned that some slight modification is needed for the 2006 Rocket III model , if you own a 2006 Rocket III please e-mail us for details. "
