As I remember it, 2003 was the only year that the ST1300 was available without the electric windshield in North America, and that was only models that did not have ABS brakes. All of the ABS equipped models also came with the electric windshield. 2004 and onward were all equipped with the electric windshield regardless of whether they had ABS brakes or not.
If this is the same ST1300 that you asked about in 2019 (
link to original post), you wrote that there was confusion about whether it was a 2004 instead of a 2003, not between a 2003 and a 2002.
There were not supposed to have been any 2002 ST1300's sold in North America, only 2003 and up. If it is a 2002 according to the VIN, it must have been brought in from outside of North America, or there is some other story behind it.
What is the tenth character, starting from the left, of your VIN? Check what is actually stamped on the steering head of the motorcycle, as opposed to the paperwork that you have.
