I believe this promotion started around November 1st as that's when I remember receiving the letter about the promotion from Triumph (being a current America owner). To participate in the promotion you MUST have the letter and take it to your Triumph dealer. This according to the letter I received from Triumph.
When I went to look at the Thunderbird around the end of December my dealer wasn't even aware of the promotion. But once I made the purchase of the Thunderbird all I had to do was show them the letter and they contacted Triumph for the details.
Which was that I could pick out any Triumph jacket I wanted. My dealer was even willing to order the jacket I wanted which they didn't have it stock, I did go with the T-bird jacket.
Then the dealer has to sent to Triumph a copy of the letter along with prove that the name listed on the bill of sale of the T-bird matches the registered owner of an America or Speedmaster. Triumph THEN will reimburse the dealer for the cost of the jacket.
VERY please with my new Thunderbird jacket...
And of course my Thunderbird!
