Hello Hello, First, I'd like to repeat some of the advice here about buying a brand new bike versus buying used. I rarely buy a brand new bike anymore... But if you insist...
First, I live in the same general area as you and know there is inflated prices but you can always drive 2 hours south, an hour north, or 1-2 hours east for a better deal. That said, I picked my Street Triple R from Mountain View OTD for 11.5k if I remember correctly.
Negotiation Preparation: Identify your Best Case Scenario (Pricing, OTD Pricing, accessories, free oil changes, maintenance, etc). Write this stuff down.
Next Identify your worst case Acceptable scenario (Pricing, OTD Pricing, accessories, free oil changes, maintenance, etc). Write this stuff down, this is your reserve (from your pov).
Next Determine your BATNA (Best Alternative to Not Agreeing): Will you look for a used bike (same brand)? Will you look at another new bike? Will you look at a used bike different brand? Whatever it is...What will you do if you can not come to a deal? Write it down.
Then, figure out what your options are in-between the best case scenario and your reserve. Create MESO's (Multiple Equivalent Simultaneous Offers) that have different prices or accessories included but yet are the same value to you. ie: you are willing to pay $500 more if certain accessories are included and installed, you are willing to pay $1000 more if you get an extended warranty included or a helmet, or free service). Just create a bunch of these offers. Present them a few at a time, combined. See where that leads.
Next, when you negotiate, do not start with the MSRP. This is known as an Anchor point. It is a suggestion made by the manufacturer and really has no bearing on the conversation. Instead, try to re-anchor the price in your favor. IE: the price offered to you is 13K. Offer 8k or 9k. Anything to get rid of the MSRP price as a starting negotiation point. This is more of a psychological tactic.
Next, don't let time be a factor in your decision. Yes, you want the bike and yes they want to sell it to you. If you are willing to wait as long as they are, negotiations will become more focused on closing the deal rather than a sale.
Finally, back up your assumptions and research the facts. IE: craigslist has same bike, few hundred miles for similar price. Why would you pay more for the same thing? Another dealer outside the area is offering ___, why should I pay __ when I can get it there?
Another tip, think about ways of expanding this 1 time deal into a relationship and at the same time expand the negotiation beyond price. IE: You have friends you can and will refer. This will be your only moto shop for service / upgrades. etc etc.
There is much much more to successful negotiations but this is a great way to start. Good luck!
