If your suggestion is to get the cheapest price, then this is ineffective. When there are a bunch of dealers selling the same bike, the best method is to email everyone of them, let them know you are comparing prices. You are not gonna visit all the dealers in person and waste your time negotiating with them. After getting the cheapest price, if you have a particular dealer you want to deal with, just show them the prove of email you got and ask to match it.
Remember, if one dealer can sell for lower price, another one can too. However not all dealers are willing to. I can tell you right off my head Steve from Factory Recreation will at least save you the pdi/freight, for both off and on road KTM, just say referred by me.
