Harley Davidson Legacy:
Founded in 1903, Harley-Davidson is an iconic American motorcycle manufacturer renowned for its V-twin engines and cruiser-style motorcycles.
Dyna Series Development:
The Dyna line was introduced in 1991, characterized by its rubber-mounted engine for reduced vibration and a more traditional Big Twin appearance. The 2007 models received the larger 1584cc (96ci) Twin Cam engine and the 6-speed Cruise Drive transmission (though some early 2007 might have had the 5-speed, the 96ci engine typically came with the 6-speed). For clarity, this manual likely covers models with the 96ci and the new 6-speed transmission, replacing the previous 5-speed unit.
2007 Model Year Updates:
The significant update for 2007 was the introduction of the 96 cubic inch (1584cc) Twin Cam engine across most models, paired with the new 6-speed Cruise Drive transmission. This manual would detail these new components.
Manufacturing Location:
United States (primarily York, Pennsylvania and Milwaukee, Wisconsin)
