I have been saying for years (and I was not the originator of the idea) that H-D should switch to a "custom order" type of system using their parts catalog as a base so that the customer could order exactly what they want for things like motor size, paint schemes, parts themes such as skulls,flames etc. That way when the bike arrives it is truly a "one of" type turn key bike.
I know they tried it a couple of years ago with a couple of Sportsters but should be available across the board so H-D could market itself as the largest custom bike builder.......
I know they may take away from the dealerships profit in after sales installs but I think they could make out better in the long run by making it easier to get service/warranty work done quickly. I would think also that pre-ordering parts to be installed at factory would help determine H-D inventory based on demand for certain things and help prevent overstocking slow moving items.
