2008 9K miles? That should be sweet as hell. Its like anything else, cables , motor seals, bearings. XB's aren't "money" pits compared to the average Japanese sport bike... the parts are actually less expensive in most cases. Yes there is a "aftermarket".. all the good engine stuff is American custom companies like Hammer Performance or Dark Horse.... custom body work usually comes from Germany "Fight Machine" or "Frank's Germany".... with Buell don't think "Bulk Aftermarket ala Honda" think more, "cottage industry" kind of like in the old days. You can make a good custom out of what is out there. Here is one I came up with , its called a "Lightningbolt"
