Kawasaki Ninja 300 Top Speed
Owner and rider discussions online sometimes note even higher observed speeds. One Reddit thread mentions reaching roughly 175 km/h indicated and seeing videos suggesting about 185 km/h top indicated speed.
Real-world top speed can vary depending on conditions like rider weight, wind, road slope, and altitude, which is why figures differ across sources and riders.
The Ninja 300 uses a 296 cc parallel-twin engine with performance and highway-focused tuning, helping it reach strong speeds for its class. Kawasaki highlights the engine’s smooth power delivery and usable top-end for cruising.
It’s designed with sportbike bodywork, dual throttle valves, and features aimed at controlled riding—factors that support stability at higher speed, not just raw top number.
A slipper/assist clutch is part of the package, helping with downshifts and rider control, useful when riding fast or in sporty situations.
1. Expect differences between indicated speed on the instrument panel and actual GPS speed; rider reports hint at indicated values being used, which can overstate real speed slightly.
For long highway runs, Kawasaki’s notes on smooth power and low vibration imply the bike is meant to cruise comfortably near higher speeds, not just sprint briefly.
