Harley-Davidson motorcycles, like any other motorcycles or vehicles, require fuel to run and will eventually run out of gas if not refueled. However, there might be some misconceptions or confusion that led to your question, so I'll try to address a few possibilities:
Fuel efficiency: Harley-Davidson motorcycles, like many other motorcycles, typically have smaller fuel tanks compared to cars or larger vehicles. This means they have a limited fuel capacity and may require more frequent refueling. However, the actual range varies depending on factors like the model, engine size, riding conditions, and riding style.
Gas gauges: Most modern Harley-Davidson motorcycles are equipped with gas gauges or fuel indicators on the instrument panel. These gauges display the amount of fuel remaining in the tank, allowing riders to monitor their fuel level and plan for refueling accordingly. The gauges can help riders avoid running out of gas unexpectedly.
Reserve fuel: Some Harley-Davidson motorcycles may also have a reserve fuel option. When the main fuel level is low, riders can switch to the reserve fuel setting, which provides access to an additional small amount of fuel in the tank. This reserve fuel is typically enough to allow riders to find a gas station and refill before completely running out of gas.
It's important to note that, despite these features, it is still the rider's responsibility to monitor the fuel level and refuel when necessary. Running out of gas while riding can be dangerous and inconvenient, so it's always recommended to keep an eye on the fuel gauge and plan refueling stops accordingly.
