The legendary development of Halley is always associated with a specific historical environment. On the Independence Day of 1905, a rider rode a Harley motorcycle to win a car race in Chicago. Since then, Harley's sales have gradually increased, the scale of production has gradually expanded, with stable sales channels, also has its own distribution office, and began production of police motorcycles. Soon after, the First World War began. Harley seized the opportunity to use the battlefield as a market, produced about 20,000 military motorcycles and gained considerable profits. In 1918, on the second day of the signing of the World War I Armistice Agreement, the Allied Corps Roy Holtz rode a Harley and entered the German territory. In the Second World War, Harley again took the express train of the arms industry and began leapfrog development. By the end of World War II, Harley produced a total of 90,000 WLA military motorcycles. The daily life of Harley and the US military has become a lingering part of the lives of these soldiers. When they returned to the motherland and saw the familiar Harley motorcycle again, it was not hard to imagine the excitement in the heart. Halley pinned their patriotic passions deep inside, and they also became Halle’s most loyal supporters.

From the beginning of its establishment, Harley has been committed to improving and innovating in machinery, appearance and other aspects, continuously improving the quality of Harley, and improving the added value of the brand through the development of various service projects.
