ST03-Z1000 Motorcycle: High-Performance Dual-Cylinder Engine with Advanced Cooling and Suspension Systems

This premium ST03-Z1000 motorcycle delivers exceptional power, reliability, and rider comfort for enthusiasts seeking a high-performance machine. Designed for both urban commuting and spirited weekend rides, it features a robust 400cc water-cooled engine that outperforms its 250cc air-cooled counterpart in torque, speed, and fuel efficiency. With a top speed of up to 160 km/h, this dual-cylinder model offers an exhilarating ride while maintaining excellent control and stability across various terrains.

Key specifications include a 6-speed transmission, hydraulic suspension at both front and rear, and disc brakes on all wheels—ensuring precise handling and safety in diverse riding conditions. The bike’s lightweight yet durable frame (140kg net weight) makes it agile without compromising payload capacity (150kg). Its 13-liter fuel tank supports extended travel, and the electric start system adds convenience, especially in cold weather or during long commutes.

Engine performance is optimized with a compression ratio of 9.2:1, advanced CDI ignition, and efficient fuel delivery using 92# gasoline. Compared to similar models, the ST03-Z1000 excels in real-world acceleration, offering 18.6 kW at 8300 rpm and 25.5 Nm of torque at 6200 rpm. This balance between low-end responsiveness and high-revving capability ensures smooth throttle response whether navigating city streets or cruising on open highways.

The motorcycle's design incorporates thoughtful engineering elements such as a 1320mm wheelbase for stable cornering, 210mm ground clearance for off-road adaptability, and 110/70-17 front and 150/70-17 rear tires that provide optimal grip and durability. These features make it ideal for riders who value versatility—not just for daily use but also for adventure touring or weekend getaways.

Manufactured under strict quality standards, the ST03-Z1000 comes packed in steel and carton packaging, ensuring safe transport for bulk orders. Minimum order quantity is 24 units per SKD package, making it suitable for dealers, importers, and fleet operators looking to expand their inventory with a reliable, high-value product.

Users appreciate the bike’s refined ergonomics, responsive braking system, and consistent performance even under heavy loads. Many riders report improved confidence when riding in traffic due to the combination of powerful brakes, responsive steering, and balanced weight distribution. It’s particularly praised by those who prioritize long-term reliability over flashy aesthetics—a true workhorse built for real-world use.

Frequently asked questions often center around maintenance intervals, recommended fuel types, and compatibility with aftermarket accessories. While regular servicing is advised every 6,000–8,000 kilometers, the engine’s water-cooling system reduces overheating risks compared to air-cooled alternatives. For best results, always use 92 octane fuel and ensure proper tire pressure maintenance for peak performance and safety.
