The Aermacchi-Harley-Davidson SX 175, a true icon of 1970s motorcycle design. Built in partnership between Harley-Davidson and Italian manufacturer Aermacchi, this diminutive two-stroke is a masterclass in compact engineering.
With its potent 172cc two-stroke engine delivering a snappy 25 horsepower to the rear wheel, the SX 175 is as agile as it is energetic. Quick-shifting transmission and a lightweight frame make it a blast to ride on twisty roads or tight city streets.
But what truly sets this motorcycle apart is its unique blend of Italian flair and American know-how, making it an irresistible choice for riders who crave something new and different.
