The mark up at the dealers is crazy. I had to buy a backrest and luggage rack when I bought my hardball because the bike I trade on had both. I had luggage etc strapped to it so I couldn't fit everything on the new bike without. It was $499 each. So $1000 for a luggage rack and sissybar. Both of those go for over $100-150 less each on ebay.
I paid $299 shipped for a new windshield off ebay where the dealer wanted $599.
The only benefit to buying from the dealer is they can add it to your bill so you can finance them with the bike if you don't want to pay out of pocket.
