What is the top speed of the NMAX155?
2 Answers
The top speed of the NMAX155 is 127 km/h. It is powered by a single-cylinder, liquid-cooled, four-stroke, four-valve EFI engine with an actual displacement of 155cc, and features Yamaha's proud VVA (Variable Valve Actuation) system, which helps reduce fuel consumption during regular riding, ensuring good fuel economy. In terms of specifications, the engine delivers a maximum power of 11.3 kW at 8,000 rpm and a maximum torque of 13.7 Nm at 6,500 rpm. According to official tests, the fuel consumption is approximately 2 liters per 100 kilometers. Combined with individual riding habits and a 7.1-liter fuel tank capacity, the estimated range should be around 250 kilometers. Regarding the chassis structure: The NMAX155 is equipped with a lightweight steel tube frame featuring a low-beam design, making it easier to handle at low speeds while providing sufficient rigidity for high-speed riding. The suspension system consists of a 100mm travel telescopic front fork and a standard twin-tube rear shock absorber (the overseas high-spec version comes with a twin-tube shock absorber featuring a gas reservoir).
As a long-time motorcycle enthusiast, I've ridden the Yamaha NMAX 155, which typically reaches a top speed of around 115 km/h. I've personally tested it on flat highways. The 155cc single-cylinder engine delivers solid power with smooth output, but actual speed is significantly affected by weight—for instance, at 70 kg I easily surpassed 110 km/h, whereas heavy loads or strong headwinds might drop it to around 105 km/h. Maintenance is crucial; keeping tire pressure optimal and oil fresh enhances performance. I love this sporty scooter for its quick acceleration, making city navigation effortless, though pushing it too hard can make the engine noise quite loud at high speeds. Overall, it's a reliable daily ride with a good balance of speed and comfort. For those chasing extra performance, upgrading the air filter or chain might add a km/h or two, but I wouldn't recommend beginners tinker excessively.
