I am ordering for USA delivery, will my Yukon come set to USA units of measurement (mph) and US top speed? Or will I need to figure that out?

All bikes come preset in the Canadian standard which is in km/h. Changing to mph is straight forward and takes few seconds. You need to go to the advanced settings on the LCD screen panel and switch the value S7 from km/h to mph.
