Zongshen is a Chinese manufacturing company based in Chongqing that produces engines for motorcycles, quad bikes, generators, snowmobiles, motor pumps, tractors, etc. Zongshen has an annual production of over 1,000,000 engines.

Zongshen's engine models, whether petrol or diesel, are some of the most popular in the world, thanks to their performance and, above all, their ideal quality-price ratio. Thus, considering the country of origin (China), the equipment is more affordable than those with a similar cylinder capacity produced in the West (for example by Briggs & Stratton in America or Wacker in Germany). They are aimed at both professional and amateur users, who need them to successfully complete various tasks around the house in the shortest possible time.
