The Kawasaki Ninja 650 is faster than the Ninja 400.
Kawasaki Ninja 650 vs. Ninja 400: Speed Comparison
When comparing the top speeds of these two popular Kawasaki sportbikes, the larger engine of the Ninja 650 gives it a clear advantage. The Kawasaki Ninja 650 can achieve a top speed of approximately 130 mph, while the Kawasaki Ninja 400 can reach a top speed of 116.7 mph.
This difference in speed is primarily due to their engine displacement, with the "650" indicating a significantly larger engine (649cc parallel-twin) compared to the "400" (399cc parallel-twin). Despite the performance difference, both models share the same ignition types and fuel systems, ensuring consistent reliability across the series.
Here's a quick comparison of their top speeds:
| Motorcycle Model | Approximate Top Speed |
|---|---|
| Kawasaki Ninja 400 | 116.7 mph |
| Kawasaki Ninja 650 | 130 mph |
Why the Speed Difference?
- Engine Displacement: The Ninja 650's larger 649cc engine produces more horsepower and torque compared to the Ninja 400's 399cc engine. This greater power output directly translates to higher top speeds and stronger acceleration.
- Power-to-Weight Ratio: While both bikes are relatively lightweight, the increased power of the 650 allows it to achieve higher velocities more efficiently.
For riders seeking maximum outright speed and acceleration, the Ninja 650 offers superior performance. However, the Ninja 400 remains a highly capable and agile sportbike, often favored for its lighter weight, easier maneuverability, and suitability for newer riders or city commuting. Both models are part of the acclaimed Kawasaki Ninja series.
