ST04-BWM2 Motorcycle Series – High-Performance, Reliable & Stylish Riding Experience

Discover the ST04-BWM2 motorcycle series, a versatile and powerful lineup designed for riders who demand performance, comfort, and durability. Whether you're navigating city streets or exploring open roads, this range of models—featuring 150CC, 200CC, 250CC, and 400CC variants—delivers consistent excellence across engine types, torque output, and fuel efficiency. Engineered with precision and built for real-world conditions, these motorcycles offer an ideal balance between sporty agility and practical utility.

Key Features That Set It Apart

Each model in the ST04-BWM2 family comes equipped with advanced engineering: air-cooled single-cylinder engines for the smaller variants (150–250CC) and a robust double-cylinder water-cooled system for the 400CC version. The 400CC variant stands out with its 6-speed transmission, offering smooth acceleration and highway stability up to 160 km/h. All models feature electric start with kick-back support, ensuring reliable ignition even in challenging weather. Braking systems include dual disc front brakes and single disc rear brakes for enhanced safety and control during deceleration. Suspension setups are hydraulic on both front and rear, providing superior ride comfort over uneven terrain.

Detailed Specifications for Informed Choice

The ST04-BWM2 series offers clear differentiation by displacement: from the compact 149.4ml engine in the base model to the high-output 367ml unit in the top-tier 400CC variant. Power delivery varies accordingly—from 8.5 kW at 8,000 rpm for the 150CC model to a commanding 25.5 kW at 7,600 rpm for the 400CC version. Torque ranges from 10 N·m at 7,500 rpm to a muscular 33 N·m at 5,500 rpm, making each bike suitable for different riding styles. Fuel economy remains efficient across all models, averaging between 2.2L/100km and 2.6L/100km depending on engine size and usage patterns. With a consistent 17.5-liter fuel tank capacity, long-distance travel becomes more convenient without frequent refueling stops.

Ideal Use Cases Across Diverse Environments

This motorcycle line is perfect for urban commuters seeking agile handling and low maintenance, as well as weekend adventurers looking for reliable performance on varied surfaces. The 150–250CC versions are excellent for daily use in cities due to their manageable weight (136–140kg), compact wheelbase (1430mm), and responsive throttle response. Meanwhile, the 400CC model appeals to enthusiasts who prioritize speed and touring capability, thanks to its increased payload capacity (150kg), improved ground clearance (170mm), and optimized cooling system. These bikes are also well-suited for rental fleets, training programs, or personal ownership where dependability and ease of servicing matter most.

User Feedback Highlights Real-World Performance

Owners consistently praise the ST04-BWM2 series for its reliability under regular use, especially in hot climates where air-cooled engines perform reliably without overheating. Riders note the smooth power delivery, particularly in the 250CC and 400CC models, which handle uphill climbs and traffic congestion effortlessly. The suspension setup receives positive reviews for absorbing road imperfections while maintaining stability at higher speeds. Many users appreciate the inclusion of CDI ignition systems across all variants, which contribute to consistent spark quality and reduced downtime compared to older points-based systems.

Frequently Asked Questions

What makes the ST04-BWM2 series stand out from similar motorcycles? Its modular design allows for multiple engine options within one frame platform, enabling buyers to choose based on performance needs rather than purchasing entirely different models. Additionally, standardized components like tires (110/70-17 front, 140/70-17 rear), braking systems, and suspension reduce repair complexity and cost over time.

Is it suitable for beginners? Yes—the 150CC and 200CC models are beginner-friendly due to their Light weight, predictable handling, and easy-to-use starting mechanism. They provide a gentle learning curve for new riders before progressing to larger displacements.

How does fuel consumption compare to other motorcycles in its class? The ST04-BWM2 series maintains competitive fuel efficiency, especially when compared to similarly powered scooters or off-road bikes. The air-cooled engines minimize parasitic losses, contributing to better mileage per liter, which is essential for budget-conscious riders.

Can I install accessories easily? Absolutely—the modular structure supports aftermarket upgrades such as LED lighting, GPS navigation units, luggage racks, and custom seat designs without requiring major modifications to the chassis or electrical system.
