The fuel consumption of the Yamaha NMAX155 is 45.2km/L. Below are the advantages of the Yamaha NMAX155: 1. Agile Handling: Although the NMAX155 appears to be a comfort-oriented touring scooter, it actually weighs only 130kg, comparable to most 125cc sport scooters on the market. Its 1340mm wheelbase is the same as the sixth-generation Cygnus, significantly enhancing its agility. Whether commuting in the city or enjoying mountain roads during holidays, it offers riders a highly enjoyable and effortless riding experience. 2. Fuel Efficiency: The NMAX155 features Blue-Core energy-saving technology, combining high combustion efficiency, excellent cooling, and low power loss. Additionally, its idle stop system automatically shuts off the engine at red lights. When restarting, the SMG Motor Generator system directly drives the crankshaft, reducing vibrations and noise during startup. This system is far more effective than the start-stop functions in most cars today, achieving a fuel consumption rate of 45.2km/L. 3. Smooth Power Delivery: The NMAX155 is equipped with a 155cc Blue-Core liquid-cooled engine that balances efficiency and performance. Along with its excellent fuel economy, the VVA (Variable Valve Actuation) system compensates for the power gap between low and mid-high RPMs, delivering linear acceleration. Its high-RPM performance is particularly impressive, making it ideal for both urban commuting and short trips.

I’ve been using my NMAX155 for almost a year and have specifically tested its fuel consumption a few times. During peak commuting hours in the city, it averages around 2.3L/100km, while maintaining a steady 60km/h on suburban roads on weekends can bring it down to 1.9L. I use the Xiaoxiong Fuel Consumption app to record every refuel—filling up the 7.1L tank with 92-octane gas gives me just over 300km. However, fuel efficiency is heavily influenced by driving habits; my friend, who enjoys aggressive starts, consistently hovers around 2.5L. Modifications also play a big role—his bike, fitted with a rear box and mount, has increased wind resistance, adding another 0.2L to consumption. Remember to maintain tire pressure at 1.8Bar (front) and 2.2Bar (rear). Last month, when my tire pressure was low, I noticeably had to refuel more often.

Just came back from a short road trip with my new bike last week, so I can share some firsthand experience. Covered 200km from Hangzhou to Qiandao Lake with two riders and luggage, the dashboard showed 2.1L/100km fuel consumption. Yamaha's official figure of 2.2L is pretty accurate, but real-world consumption varies greatly with road conditions. The instant fuel consumption scared me when it hit 3.8L climbing mountain roads, but dropped to 1.5L when braking downhill. The fuel warning light starts flashing with about 40km range left. After the last fuel bar disappeared, I refueled 6.3 liters, proving there's still 0.8L reserve. Fuel efficiency improves slightly after - mine dropped by 0.15L after the 1500km first service.

Actual tests show significant fuel consumption differences at various speeds: 2.0L at a steady 60 km/h, but it rises to 2.4L at 80 km/h. Winter consumption is 0.3L higher than summer, and using 95-octane fuel can extend range by 30km. Initial consumption was 2.5L when newly purchased, but improved significantly after the break-in period. Don't overfill engine oil - exceeding the upper limit will definitely increase fuel consumption.

Modifications have a huge impact on fuel consumption! Just switching to semi-slick tires adds 0.2L per 100km. The most fuel-efficient driving method is maintaining a steady speed of 50-60 km/h. Models with TCS can save 5% fuel. Cleaning the transmission case every 1,000 km is crucial, as dust buildup significantly reduces transmission efficiency. For gas stations, Sinopec is recommended for better fuel quality and longer range.

Fuel consumption measured in Chongqing, the mountainous city: 2.8L with AC on in summer, which amazed me. Later, I learned to coast downhill by releasing the throttle to let the VVA Blue Core system cut off fuel automatically, and drive within the ECO light range on flat roads. Avoid sudden braking when carrying passengers or cargo, and use engine braking assistance to save fuel. The official claim is a theoretical range of 350 km, but in reality, you need to find a gas station at around 280 km. Checked the spark plugs; carbon buildup after 15,000 km can increase fuel consumption by about 0.4L.
