Vehicle Information
Suzuki DR-Z400S Motorcycle - Dual-Sport (2000-2024)
The Suzuki DR-Z400S is a popular dual-sport motorcycle produced from 2000 to 2024. It is known for its consistent design and a 398cc, liquid-cooled, single-cylinder, DOHC, four-stroke engine, producing approximately 39 horsepower. It used a Mikuni BSR36 carburetor throughout this period. The DR-Z400S maintained a remarkably consistent core design. Minor updates included suspension changes (2002), a cam chain tensioner (2003), a primary drive gear (2004), and vibration damping (2005). The engine remained carbureted without major redesigns. Other variants like the off-road DR-Z400E and the Supermoto DR-Z400SM (introduced 2005) were also offered, but the DR-Z400S itself saw only minor refinements. No major generational overhaul occurred within the 2000-2024 range. FAQ:
