Bulletproof Engine Reliability
The DR-Z400S is renowned for its near-indestructible 398cc liquid-cooled engine that routinely surpasses 50,000+ miles with basic maintenance. It's one of the most reliable dual-sport engines ever produced, making it a top pick for budget-conscious riders.
Watch the Carb & Valves
Common issues include a clogged carburetor from ethanol-blend fuel sitting unused, and valves that can tighten over time requiring periodic inspection every 6,000 miles. Always ask sellers for valve adjustment history before buying.
Strong Resale Value
The DR-Z400S holds its value exceptionally well due to its long production run (2000โ2019) and universal parts availability, often selling for 70โ85% of original MSRP even after several years. Demand consistently outpaces supply in the used market.
