A lot of dealers are no longer carrying the 130 rear tire, cause it's old stock, for older bikes. Good luck getting a dealer to stock parts for a 10 year old bike, unless they're cross-over parts that fit newer models.
Federal goverment only requires MFGers to carry (not stock, just make available) parts for up to 10 years on any given make/model.
Almost everything now has the 140 rear tire (MU8516), 150 or even wider with the FXD series and the FL series. those are 160/180 and 200. I believe the 140 is the new 130 in a lot of places.
