Some good news!
HD has basically been telling 09 1125 owners to go @#$% themselves over the charging issues on the '09 1125. HD customer service basically told me the same thing when I asked if they would install the 08 charging system on my 09.
EBR just released a kit for the 09 1125. No specs are listed, but the stator and rotor look to be the same as the 08 parts.http://www.erikbuellracing.com/store/models/1125r/moderate-output-low-heat-alternator-kit.html
It's not cheap, but that about half the price that HD is charging for the 08 stator/rotor/cover assuming you can even get them.
This makes me feel a lot better about keeping my 1125R long term.
