My understanding is that the bike was first made in late 2012, but was sold (in the US at least) as a 2013 model year. Mine is a launch model, used as a demo. I bought it in 2013 (after it was a demo for a bit), and it has dates of mid-2012 on some of the components, but it has a 2013 VIN.
I don't know how many have been made, but I did see that:
The center stand recall affected 416 units in the United States
The fuel tank recall affected 513 units in the United States
The ECU recall affected 2800 units (this includes 2012-2014 Explorers as well as 2013-2014 Trophys)
The documents filed with the government concerning recalls can be found here:
