Dan,
The two things that come to mind are that the $80 price was for the wrong item or it was for a repriced item. KTM is trying to bring their prices down on a lot of stuff. Heim joint kits, for instance, used to be about $70 and now they're about $40.
It's nice of KTM to do that but sometimes dealers get screwed. If a good dealer stocked up on heim joint kits at the old price, he's going to have a heck of a time getting rid of them when everyone else is selling them for a lot less.
