The fuel tank capacity of the pit bike is from 2.5 to 4 Liter. But some manufacturers provide a bigger tank that has a capacity of as much as 7.5 Litre.
A pit bike is originally a small bike. It was invented for off-road purposes. But with the passage of time, high popularity and usages made the motorbike manufacturers think again to go to mass production of this. As it was small by its origin, it is common to have a smaller fuel tank.
Why do most Pit bikes come with a small fuel tank?
Pit bike the successor of the dirt bike is designed to run off-road and trail. Moreover, it is used to pass through forests and hilly areas. Riders have the history to get fun to ride on those rugged lands. They enjoy the elevation caused offered by the suspension system of the pit bike. So in consideration of these purposes, one doesn’t need huge fuel because he is not going to pass over a long path.
Fuel tank capacity by brand
KTM seems to provide the bigger capacity fuel tank. Let’s have a look at others.
2.5 to 7.5 liter
2.5 to 3.8 liter
3.0 to 3.4 liter
3.4 to 6.1 liter
2.6 to 7.5 liter
1.0 to 5.5 liter
2.4 to 4.5 liter
How much fuel tank matters
The volume of the fuel tank is measured in design as of the motorbike size, power and speed. The purpose of the motorbike also plays a role in the capacity of the fuel tank. The motorbike that is designed for a long journey is designed with a high capacity of fuel intake. But racing motorbikes are provided with low fuel space to reduce the overall weight. Even motorbikes for adventure are also made with small fuel tanks because those bikes are used in various hilly areas. These bikes are used also for a high jump. During these moves, the bike goes upside down from 70 to almost 360 degrees. So, a heavy volume of liquid fuel will cause fuel leakage.
Relation between Engine CC rating and fuel tank capacity volume.
The relation is not direct. Low cc rating engines are offered with small size pit bikes. So, a brand small size bike needs less amount of oil to run its small engine. This is referential information. Still, some manufacturers provide almost the same capacity fuel tank to its all-size pit bike. Pit bike and Thumpstar seem to provide the same size fuel tank to all of their motorbikes. However, those bikes that offer small fuel tanks seem to provide a high compression ratio which is around 25:1. It's more efficient for energy saving.
Can I replace the fuel tank with a bigger one?
It's never recommended to replace the fuel tank with a bigger one. There are several problems that can arise. A bigger fuel tank can misfit to your bike causing loose-fitting and odd-looking. Second, a heavier load than that of manufacturer design on a bike might cause poor balance because the tank is in front of the rider. Finally, a higher fuel volume will cause more gravitation pressure on the carburetor that might cause a wrong supply ratio of fuel and air, resulting in the bike producing abnormal combustion and poor energy.
How is the fuel mileage in a pit bike?
A average pit bike milage around 25 - 40 kilometer, its depend on the pit bike engine size.
A pit bike is less fuel-efficient due to its nature of use. Rather it's not also measured on the basis of mileage regarding how far it can go per gallon. Gallon is a US unit of measuring liquid substances. The unit related to the global unit Liter like 1 gallon = 3.8 Liter.
A pit bike or a dirt bike is made to fight against the resistance and go forth. A pit bike is an off-road bike and so it faces more resistance to run. More resistance needs more power every moment. Even it is less likely to use gravitational energy to keep running for a period of time without energy from the engine. When a motorbike runs on the plain road, it can use every single push force at least a few couples of seconds to run the bike automatically.
But pit bike runs on rugged land that provides resistance every moment so the engine also should keep generating more power to bypass the resistance and keep over. This way a high amount of fuel intake is necessary to the engine for faster combustion.
Exact reference to mileages
A 50 cc pit bike mileage is around 100 MPG while it’s 90 MPG for a 125 cc pit bike. In this consideration, it seems a small engine can run further because of its small ambient body weight. So, heavier weight both by fuel or engine will cause power losses. Since a pit bike offers about 2.5 to 7.5 gallons, riders can go 2.5 miles to 7.5 miles as of their motorbike tank capacity. I
Since there are so many brands making pit bikes the mileage isn't certain for all brand pit bikes. It often changes according to many parameters of a bike. Manufacturers are also trying their best to make the bike energy efficient.
What size of the fuel tank to go for?
As most of the manufacturers offer a medium side of 3 to 4 liter, you should go try that. Although some brands provide up to 7.5 liters, they are reported to be less powerful at the passage of friction. As for the standard pit bike features, a pit bike providing a fuel tank of 4.5 capacity seems good for all purposes.
Along with the fuel intake, it's also good to look for the compression ratio. It's one of the points of energy efficiency that works on the basis of engine cc rating. A higher compression ratio utilizes fuel more smartly but produces the same power e.g. some 50 cc engine offers a 25:1 compression ratio which is better than many other bigger engines.
