Almost guaranteed if you actually go to the dealer ready to make a deal, they will give you a better deal than they would by email.
The last bike I bought was a CB300F from a large dealer. I knew what was a fair price which was less than they wanted of course. After the salesman went back and forth a couple of times to the sales manager, he came over to tell me to try and close the deal. He gave me his final best deal, but it was still over my price $150. I thanked him and headed for the door. Reaching for the door, some guy I hadn't even seen before called my name and stopped me. He said they would take my offer, which they did. This guy appeared out of nowhere. When I saw him I asked where he came from and some of the other sales people snickered, because apparently this is how they do business. The smaller dealers don't work this way, but the big ones do. They are experts at maximizing profits since they have a lot of fingers in the pie. But in the end, they want to sell bikes for a profit...any profit and if you are there with money, they will probably sell it to you. You must be prepared to walk away though without buying a bike and you should know what a fair price is. I sure wouldn't begin with their asking price, then add taxes, title, shipping, etc. on top of it to get the fair price. Also, if you are planning on buying other things like gear, I would include that in the negotiations. Otherwise, the first thing they will do AFTER you agree on a price is try to sell you more stuff. Again, this is the way large dealerships work. It's the same process as buying a new car and if you aren't careful, you can pay $1000+ too much. It always helps to go to a second dealer when trying to buy a car or bike too. You can go back and forth between 2 dealers a long time until one say, "we can't beat that price." Then you know you are getting close to a fair price.
If you follow other motorcycle forums, you will see what I mean. I bought a Honda Grom a year or so ago. Pre-ordered it with a negotiated price of $3600 which was a fair price. Thing is, the bike was very popular and in short supply. I got mine for $3600 and it turned out to be the only bike that dealer got in, but people were pay $4600 for the same bike from other dealers. A couple of people got their bikes cheaper than $3600 too.
While we don't want to screw our dealers, you don't really have to worry about that. They won't make a deal with you if they aren't making money.
