1981 Addicks Advertisement
This ad appeared in an early 1981 issue of “Bicycle Motocross Action”. I include it because it is a good shot of the bike. The model could be a 1980 since it appeared in a very early 81 issue of the magazine.

1977 Advertisements
The below advertisement talks about the “new” SR frame. This appeared in the August 1977 issue of Bicycle Motocross Action. That would indicate the bike came out in 1977. The ad also says the bike was tested for three years? Meaning they built the first prototype in 1975.
