Harley dealerships seem to vary greatly depending on how much local competition they have. Some charge way over MSRP due to lack of competition and seem as though they won’t budge. Some start at MSRP and can be worked down. But they can all be negotiated with. Just depends on how much of a tool your salesman is.
If it’s a Sportster you’re looking for I’d go the used private seller route. The used market’s very flooded with Sportsters for sale.
