Motorcycles are amazing machines that provide a unique experience on the open road.
But like any other machine, motorcycles need fuel to run. This fuel is stored in the motorcycle’s gas tank.
We will discuss the different types of gas tanks and their corresponding fuel capacities.
Type of Motorcycle Gas Tanks
The most commonly found material for a motorcycle gas tank is a plastic or metal.
These tanks vary in size depending on the make and model of the motorcycle, but are usually designed to hold a specific amount of fuel (usually about 2 to 7 gallons).
Some newer models may feature aluminum alloy tanks that are lightweight and more aerodynamic than traditional plastic tanks.
Another type of gas tank is the fuel cell tank. These tanks are typically made of a strong, lightweight material such as carbon fiber or Kevlar and feature an internal bladder made from a synthetic rubber-like material. Fuel cells offer superior strength and durability compared to plastic or metal tanks, but they are usually more expensive.
Motorcycle Gas Tank Styles
The shape and design of a motorcycle’s gas tank has a pretty big impact on its overall style and appearance.
Different types of motorcycles can usually be quickly identified by a look at the tank.
Choppers, bobbers, and cafe racers builds can all benefit from a thought-out gas tank style.
If you’re designing a custom motorcycle, thinking about the style of gas tank you’re going to use is an important consideration.
Some popular styles for custom builds include:
- Peanut gas tanks.
- Sportster-style tanks.
- Coffin-shaped tanks.
- Cafe-style tanks with knee dents.
- Split tanks/bobbed gas tanks.
If you’re going for a truly custom look, you can find a metal fabricator to build you a totally custom gas tank as well.
How Much Fuel Can a Motorcycle Gas Tank Hold?
Fuel capacity varies widely among motorcycles, depending on the size and type of tank.
In general, the larger the motorcycle, the larger gas tank capacity it will have.
Smaller models may have tanks that hold two to three gallons, while larger models can hold up to six or seven gallons. Fuel cells typically offer more fuel capacity than traditional plastic or metal tanks due to their more efficient design.
In addition to fuel capacity, it’s important to consider the range of a motorcycle.
Smaller bikes with lower fuel capacities may have less range, while larger bike models with higher capacity tanks can offer longer ranges.
| Motorcycle Engine Size | Average Fuel Capacity |
| 50 to 125cc | 1.5 to 3.5 gallons |
| 250 to 500cc | 2 to 4 gallons |
| 600 to 750cc | 4 to 6 gallons |
| 800 to 1000cc+ | 5 to 9 gallons |
How to Store a Motorcycle Gas Tank
When filled, gas tanks should always be stored in an upright position to prevent fuel from leaking or spilling.
If you need to transport the tank, make sure that it is securely fastened and covered with a protective material such as bubble wrap. It’s also important to keep the tank away from any sources of heat or direct sunlight, which could cause the fuel to evaporate and damage the tank.
For long term storage or winterization, you can either:
- Drain, clean and lubricate the tank completely.
OR - Fill up the tank to its capacity and add a fuel stabilizer.
Storing a motorcycle gas tank correctly is one of the most important steps to ensuring that your bike runs smoothly on the open road.
Improper storage can lead to gas tank rust or clogged carbs.
With these tips in mind, you can ensure that your gas tank stays safe and secure.
