ST04-BWM2 Motorcycle Series: High-Performance, Reliable & Versatile for Global Riders

The ST04-BWM2 motorcycle series represents a powerful blend of engineering precision, rider-focused design, and adaptable performance across four distinct engine variants—150cc, 200cc, 250cc, and 400cc water-cooled models. Whether you're commuting through city streets or exploring open roads, this range delivers consistent power, refined handling, and robust durability tailored for riders worldwide aged 18 and above.

Key Features That Set It Apart

Each model in the ST04-BWM2 lineup is built around advanced 4-stroke single-cylinder engines (except the 400cc variant, which features dual cylinders), offering smooth acceleration and efficient fuel consumption ranging from 2.2L/100km to 2.6L/100km. With air-cooled systems on smaller engines and a water-cooled setup on the top-tier 400cc version, thermal management ensures stable operation under diverse conditions. The CDI ignition system provides reliable starts every time, while electric plus kick-start functionality enhances convenience in any environment.

Braking performance remains uncompromised with front double disc brakes paired with rear single disc brakes across all models—an ideal balance between stopping power and weight efficiency. Suspension systems are hydraulic on both front and rear, delivering responsive damping that absorbs road imperfections without sacrificing control during cornering or high-speed riding.

For those seeking agility and comfort, wheelbases remain consistent at 1430mm, with tire sizes optimized for grip and stability: 110/70-17 front and 140/70-17 rear. Ground clearance varies slightly—from 160mm on lower-displacement units to 170mm on the 400cc model—offering improved clearance over rough terrain or uneven surfaces commonly found outside urban settings.
