After re-reading the article (first saw it years ago) it does not say every ST1300 produced was tested before leaving the factory but says 'Every ST1300 produced since has been test-ridden before leaving the factory. '
Correct, but I would think that the number of ST1300's that may have been released to the public prior to this policy being introduced is so small that they are statistically irrelevant.
The
since was very, very early on in the motorcycles production.
The ST1300's first production year was 2002. These events all occurred during the 2002 press launch of the ST1300. The press launch typically, but not always, happens well in advance of a new motorcycle model being delivered to any retail purchaser. This new process of testing every one prior to release was introduced immediately after this press launch. Given the timing of these events, the number of ST1300's that may have been released to the public before this test procedure was introduced would be so small that it is doubtful that they would have any statistical influence.
I don't believe that any 2002 ST1300's were available for sale in North America. If the first ST1300 model year sold in North America was 2003, it is very doubtful that there were any ST1300's sold in North America that were not subjected to this new process and were not tested prior to leaving the factory.
