Looking for a budget-friendly yet high-performance enduro bike? The Hengjian S7-Z300 might just be the answer. Priced at $3,699, this Chinese-made 2-stroke dirt bike is turning heads with its KTM-inspired design and impressive specs. But is it worth considering for serious off-road riding? Let’s dive into the details.
Who Makes the Hengjian S7-Z300?
Hengjian Motorcycles is a major manufacturer based in Chongqing, China—the country’s motorcycle mecca. They produce a variety of bikes, including dirt bikes for well-known brands like GPX, which has a solid reputation in Western markets.

• 58 horsepower @ 8,500 RPM
• 52 Nm torque @ 7,000 RPM
• Adjustable power valve (great for hard enduro tuning)
• 6-speed gearbox
• Premix fuel system
• Electric starter
The KTM-like engine also makes finding spare parts easier, a big plus for maintenance.

• 9L fuel tank
• 940mm seat height (tall, but typical for enduro bikes)
• 1480mm wheelbase
