The range of the 400x is 450km. 2021 Honda CB400X: It is an adventure motorcycle launched by Honda Wing, with dimensions of 2085mm in length, 830mm in width, and 1370mm in height, and a seat height of 807mm. The 2021 Honda CB400X is equipped with an inline twin-cylinder, four-stroke, liquid-cooled 400cc engine, delivering a maximum power of 33kw and a maximum torque of 37nm, paired with an international 6-speed transmission. The curb weight of the motorcycle is 195kg, and the fuel tank capacity is 16.5 liters. Fuel consumption calculation method: First, fill the vehicle's fuel tank completely, then reset the odometer or record the current mileage information. After using the vehicle for a period of time, refuel again. The amount of fuel added divided by the mileage between the two refueling instances multiplied by 100 gives the vehicle's fuel consumption. The Honda CB400X has a fuel consumption of approximately 5 to 6 liters per 100 kilometers, with a fuel tank capacity of 16.5 liters.

















I recently took my 400X for a trip to Yunnan and found its range quite impressive. According to official data, with a fuel tank capacity of around 17 liters and an average fuel consumption of approximately 4.2 liters per 100 kilometers, it can easily cover 350 to 400 kilometers on a full tank. However, when driving faster on the highway, the fuel consumption jumps above 5 liters, reducing the range to around 320 kilometers. On mountainous roads with lots of uphill climbs, it can only last a little over 300 kilometers. From experience, the heavier the load, the shorter the range, so I try to travel light on long trips. Before filling up, I check the map and plan gas station stops within 250 kilometers for safety and peace of mind.

As a frequent motorcycle rider, I've tested the 400X's range several times. The fuel tank typically holds 17 liters, with an official fuel consumption of 4 liters per 100 kilometers, theoretically allowing a range of 425 kilometers. However, real-world conditions introduce many variables. For instance, at speeds exceeding 100 km/h, increased wind resistance raises fuel consumption to 5 liters, reducing the range to around 340 kilometers. In urban traffic with frequent stops and starts, the range can drop below 380 kilometers. I recommend regularly checking tire pressure and air filters, as these details can improve fuel efficiency, helping to maintain a stable range above 370 kilometers. Planning your trip before refueling is more reliable.

The 400X offers sufficient range for daily commuting. I use it for commuting to and from work, and each tank of fuel lasts about 350 kilometers on city roads, requiring only one refuel per week. For short trips, a 30-kilometer journey hardly raises any concerns about fuel levels. However, for long-distance trips such as interprovincial travel, it's advisable to check the fuel gauge every 200 kilometers and prepare for a gas station stop to avoid running out of fuel midway. The original fuel tank is well-designed, providing a normal riding range between 360 and 400 kilometers. Adjusting riding habits based on speed and load can help save some fuel costs.

From a safety-first perspective on the 400X's range, as a seasoned rider, I always keep an eye on fuel levels. The standard range is approximately 380 km based on steady riding. However, in rainy conditions or on slippery mountain roads, wheel spin increases fuel consumption, potentially reducing the range to 340 km. I always carry a portable fuel canister for emergencies, adding about 40 km to the range. It's advisable to check the fuel pump and filter before departure to ensure the system is functioning properly. This way, a full tank can last nearly 400 km, ensuring safe long-distance travel without unexpected incidents.

From a modification perspective, let's talk about the 400X's range. The stock range is around 360 kilometers, which I increased to 450 kilometers after adding an auxiliary fuel tank. The base fuel tank holds 17 liters, with a fuel consumption of 4 liters per 100 kilometers. Riding habits are key: smooth acceleration and less braking can reduce fuel consumption to 3.8 liters, naturally extending the range. However, aggressive high-speed riding might drop it to 320 kilometers. Regularly cleaning the engine chain and other minor adjustments can stabilize the range above 380 kilometers, which is very practical for long-distance riders.
