Dammit - thinking about this in the shower this morning
I'm guessing by "elasticity" in the economic sense, you're saying that the dealer isn't going to budge on the price because he knows that he can sell the bike for full MSRP to the next guy if you don't want to pay?
(ref: If I lower the price of my product, how much more will I sell?")Me and Economics? Not so much...
But yeah, I think there's that, but also there just isn't a lot of margin for the dealer to mess with. The guy I worked for in High School used to say he had to make 20% at the end of the day, and that meant selling some stuff at 200% an some at 5%. Just to give you an idea, the margins that were mentioned to me (back in 2010-11, mind you) were about 7% on a bike - a little more on a Zero, and less on a Brammo.
I can't remember what the deal is with Zero, but in the camera biz we had to buy our cameras outright, or lease them, even our demo units. I don't think that's how the automotive market works, quite, but not sure... At any rate, there's a cost for just keeping the bikes in the shop, which chips away at your margin by the day...
