What is the top speed of Kawasaki 400 in first gear?
3 Answers
The Kawasaki 400 can reach 80 kilometers per hour in first gear. The speed ranges for other gears are as follows: 2nd gear up to 135 km/h, 3rd gear up to 135 km/h, 4th gear up to 135 km/h, and 5th gear also up to 135 km/h. Below is an introduction to the Kawasaki 400: Power Configuration: The Kawasaki 400 is equipped with a water-cooled parallel twin-cylinder engine, which delivers a maximum horsepower of 45ps at 10,000 rpm and a maximum torque of 38N.m at 8,000 rpm, with an actual displacement of 399cc. It is positioned as Kawasaki's entry-level sports bike. Appearance: The Kawasaki 400 has a seat height of 785mm, which is about 100mm lower than typical models like the CFMoto 250 and 150, providing a more comfortable riding posture. The bike weighs 168KG, which is 6.8KG lighter than the previous generation, featuring a more robust frame while maintaining overall lightness and stability.
When riding a Kawasaki 400, the top speed in first gear is around 50 kilometers per hour. I often use it in the city, and it's quite handy for starting at traffic lights—just a gentle twist of the throttle gets me to 45-50 km/h. However, don't rev it too hard, or the engine noise becomes loud and it's prone to overheating. First gear is mainly for strong low-speed torque and quick acceleration, but it's not suitable for prolonged high-speed riding because the high RPM can wear out the transmission components. For daily riders like me, I recommend shifting to second gear around 40 km/h—it saves fuel and protects the bike. Tire pressure and riding load can slightly affect the speed, so maintaining proper tire pressure is crucial. Kawasaki's design leans toward practicality; first gear is short and powerful but not meant for high speeds. Safe riding is the priority—don't imitate reckless speedsters.
From a maintenance perspective, the Kawasaki 400's first gear ratio sets the top speed between 48 to 55 km/h. I've monitored the engine RPM—lingering near the redline is inadvisable as it accelerates chain tension loss or oil degradation. First gear delivers strong torque for starting, but exceeding 55 km/h risks clutch burnout. For daily riding, shifting up around 40 km/h extends transmission lifespan. Regularly inspect sprocket wear and fluid conditions; scheduled maintenance preserves performance. The Kawasaki balances well—first gear offers robust power but isn't designed for high speeds. Ignoring this invites costly repairs.
