Brand History:
Harley-Davidson is an American motorcycle manufacturer founded in 1903, renowned for its cruisers and touring motorcycles. The SS SX series represents their foray into smaller displacement, sporty models during the mid-1970s, often aimed at younger riders or those seeking lighter, more agile machines.
Model Lineage:
The SS SX models were part of Harley-Davidson's efforts to diversify its product line beyond traditional large-displacement V-twins. These models often shared components with Aermacchi, an Italian manufacturer that Harley-Davidson had a significant stake in during that period, allowing for efficient development of smaller displacement bikes.
Manufacturing Location:
Likely manufactured in collaboration with or based on Aermacchi designs, potentially in Italy and/or assembled in the USA.
