The top speed of the domestic Ninja is around 130 kilometers per hour. Conditions to reach the top speed: Suitable road surface is required, and the car needs to be shifted into the overdrive gear. For example, for a 5-speed car, some cars have the 4th gear as the overdrive gear, while others have the 5th gear as the overdrive gear. After shifting into the overdrive gear, press the accelerator to the floor. Theoretically, the car will reach its top speed when the "engine speed" reaches the "maximum power corresponding speed". Meaning of top speed: It refers to the maximum driving speed that a car can achieve under windless conditions on a level, good asphalt or concrete road surface. The top speed mentioned here is data provided by the manufacturer and is for reference only, and does not represent PCauto's actual test data.

I've ridden quite a few domestic small Ninja-style motorcycles, usually with a displacement around 250cc, and they can reach a top speed of about 140 km/h, depending on your weight and road conditions. For example, last weekend I tested my bike on the highway—with a tailwind, the speed could go up to 145 km/h, but with a headwind, it dropped to around 130 km/h. Maintenance is also crucial; low tire pressure or a loose chain can reduce speed by 5-10 km/h. I recommend new owners check the chain tension and tires before every ride to maintain speed stability. Overall, these small-displacement sports bikes are more than enough for overtaking in the city, but don’t push too hard on the highway—safety first.

I work at a repair shop and often service these small-displacement sports bikes. For domestic models like the Ninja, the top speed typically ranges between 120 to 150 km/h. It largely depends on engine tuning: a 250cc single-cylinder engine producing 15-20 horsepower usually hits around 140 km/h under standard conditions. However, if the air filter is clogged or spark plugs are worn, it can drop below 130 km/h. I've serviced many owners' bikes - when acceleration feels sluggish, it's time to change the oil and drive belt. Regular maintenance prevents speed loss, and every service should include brake system testing. High speed means nothing if the brakes fail - that's truly dangerous.

I absolutely love riding this kind of motorcycle, especially domestic models like the Little Ninja. It's incredibly cool to ride around town. The top speed can reach around 140 km/h, which is thrilling enough on suburban streets, but don't expect too much. I've tried going full throttle on flat roads, and the wind pressure feels intense. Upgrading the exhaust pipe and shock absorbers can improve performance slightly. However, safety measures shouldn't be overlooked—it's best to wear a full-face helmet and protective gear. Maintenance is simple; just change the cleaning oil regularly. When riding, avoid prolonged high-speed runs to prevent engine overheating and power loss.
