Generally, the reserve fuel tank capacity of a 125cc cross motorcycle is about 2 liters, which can run about 70 kilometers. How to use reserve fuel: Turn the fuel tank switch to the upper position: If the fuel tank switch is turned to the upper position, it means the motorcycle's reserve fuel is activated. The so-called reserve fuel does not refer to a hidden compartment in the fuel tank, but when switched to this position, the fuel outlet position is lower, so this setting can basically drain all the fuel in the tank. Usage of reserve fuel: It is generally used when there is little fuel left in the tank or when the normal setting no longer supplies fuel. If there is still enough fuel in the tank, it is better not to activate this fuel tank setting.

When I'm driving my small car around the city, a 125-liter reserve fuel tank is quite a substantial backup. Generally speaking, this amount of fuel can last for about 1,800 kilometers, but the exact distance depends on the vehicle's condition and my driving habits. My compact car isn't too fuel-thirsty, averaging around 15 kilometers per liter, so 125 liters multiplied gives approximately 1,875 kilometers. If the roads are clear and I maintain steady speeds on highways, fuel efficiency might improve further; however, during city traffic jams or aggressive acceleration, consumption can spike to 20 liters per 100 kilometers, reducing the range to roughly 1,250 kilometers. I've also considered carrying extra fuel for road trips—it's actually quite convenient, but it's important to ensure the fuel doesn't expire or absorb moisture. Regular checks on fuel quality are advisable to avoid potential fuel line issues, which can be a real headache. For long drives, I recommend keeping a basic toolkit handy to top up fuel if levels get too low—it saves trouble and provides peace of mind.

Will upgrading from 125 to 150 cylinder kit increase speed?

Upgrading from 125 to 150 cylinder kit will not increase speed, but it can improve the car's climbing ability. The following is a related introduction about vehicle speed: Overview: Vehicle speed refers to the distance traveled by a car in a unit of time, referred to as speed, and the commonly used units are kilometers/hour or meters/second. Vehicle speed is one of the three parameters describing traffic flow and plays an important role in the study of traffic flow theory. Others: Vehicle speed can also generally refer to motor vehicle speed. To adapt to different purposes, vehicle speed is mainly divided into spot speed, section speed and design speed. Spot speed is the instantaneous speed at which a car passes a specified point on the road. Design speed is the speed formulated to determine the design indicators of various geometric elements of the road and make them coordinated with each other.
