This is a great question. I got one of the early runs. My buddy bought one a few months later and there were some subtle differences to his bike. Different fasteners, a gear shift sticker, stuff like that.
AFAIK the 10th digit of the VIN is the year model, but not necessarily the year of manufacture. The 10th digit of my Terra is D. D=2013. I bought the bike in Dec 2012.
THere is no on line VIN decoder for the Terra/Strada but the decode capability to determine Mfr date is in the GS911
Don't think GS-911 tool decodes VIN, think that info is written in to the ECU as clear info, first time SW is loaded up on the ECU unit. That is the nice benefit of be able to read ECU info.
There is a little more to it than that, consider how an auto scan in either Dealer Diags or GS911 works, there are many parameters which may look like plain language in a report but are decoded in different ways to give the plain language report.
