What Buyers Should Know
Bulletproof Parallel Twin
The Z400's 399cc parallel-twin engine is shared with the Ninja 400, widely regarded as one of the most reliable small-displacement engines on the market. With proper oil changes, these motors commonly exceed 30,000 miles without major issues.
Strong Resale Value
The Z400 holds its value exceptionally well due to high demand among new and intermediate riders. Used models typically sell for 80-90% of MSRP within the first two years, making it one of the better-retaining bikes in its class.
Watch the Exhaust Headers
A known cosmetic issue is premature rusting on the exhaust headers, especially in wet climates or if the bike was stored improperly. Inspect them closely before buying and budget for aftermarket headers if corrosion is present.
