In the following paragraphs, we’ll take a closer look at the motorcycle fuel capacity figures according to the main engine categories.

How Many Gallons of Gas Does a Motorcycle Tank Hold?

The Fuel Capacity of Lightweight Motorcycles

From the tiny Honda Groom to the more powerful 300-400cc models, the fuel capacity of lightweight motorcycles varies widely.

You can find the smallest fuel tanks in the 50cc motorcycles, as many of these machines offer a fuel capacity of 1-3 gallons.

If you are looking for a bigger bike, 125-250cc motorcycles typically have a fuel tank of up to 4 gallons and get around 50-130 MPG. The most powerful motorcycles in this category are powered with 300-400cc engines and offer a fuel capacity of 3-5 gallons.

Middle-weight Motorcycle Gas Tank Sizes

When it comes to middle-weight motorcycles, it’s safe to say that most of them come with a 3-7-gallon fuel tank. The popular 4-cylinder 600cc-950cc sportbikes can typically hold 4-6 gallons.

If you are looking for a higher fuel capacity, you should take a look at the adventure and touring bikes. Many of them have a bigger fuel tank, which offers a fuel capacity of 5-8 gallons.

These machines are meant to cover long distances, so the designers tried to achieve the highest possible fuel ranges.

Heavy Motorcycle Gas Capacity

Finally, let’s talk about heavy motorcycles.

These machines are typically powered with 1000-2000cc engines, which can produce up to 300 HP.

And to feed these ponies, you need plenty of gas! This is the reason why the fuel capacity of heavy motorcycles ranges from 4 up to 8.5 gallons.

Weight is always a big concern on a sportbike, which is why the fuel capacity of most 1000-1300cc sport motorcycles is as low as 4-5 gallons.

You can find slightly bigger tanks on full-size cruiser motorcycles, as the bikes in this category can hold about 4.5-6 gallons of gas.

Are you wondering which motorcycle has the highest fuel capacity?

Which Motorcycle Has the Largest Fuel Tank?

There is no question that Boss-Hoss cruiser motorcycles have the biggest fuel tank on the market. These large cruisers feature 6000-7500cc engines, which put out an amazing 400-600 HP. As you might assume, these engines are quite thirsty. To get a reasonable fuel range, Boss-Hoss motorcycles come with a generous 8.5-gallon fuel tank.

If that isn’t enough for you, auxiliary fuel tanks are also available for these machines with a capacity of 2-4 gallons.

Regarding “ordinary” motorcycles, 700-1300cc adventure bikes have the highest fuel capacity right now. Some examples for gas tank sizes in this class are as follows:

  • BMW R1200RT: 6.6 gallons
  • Honda ST1300 Pan European: 7.7 gallons
  • BMW R80 G/S Paris Dakar: 8.45 gallons

What is Reserve Fuel Capacity in Bikes?

Reverse fuel capacity in motorcycles refers to a portion of the gas tank’s fuel capacity. The benefit of this feature is that it can protect the rider from running out of fuel. When the level of gas drops below a certain level in the tank, the rider can access the reserve fuel by using the “reserve switch.”

Do all Motorcycles Have a Reserve Tank?

Contrary to popular belief, the majority of motorcycles feature only one fuel tank. This means that there is no separate “reserve tank” in most motorcycles! Instead, the reserve and main fuel settings are using gas from the same tank. The trick here is that there are two outlets installed on the gas tank of motorcycles.

The “reserve fuel outlet” is located near the bottom of the tank, while the normal outlet is located higher up on the tank.

With the reserve switch (also known as a reserve valve) you can choose which output you want to use. There are typically three positions: NORMAL, RESERVE, and OFF.

Here’s a great video on how a motorcycle’s reverse valve works:

Can You Run Your Motorcycle on Reserve All the Time?

Yes you can run your motorcycle on reserve all the time, however it’s not recommended. The reserve valve is on your motorcycle for reason, as it can save you from running out of fuel. If you use your bike on reserve all the time you risk completely draining your tank before you even notice.

This can easily happen especially on those motorcycles which are not feature fuel gauge.

How do You Put Extra Gas on Your Motorcycle?

If you mainly ride in developed countries, refueling your bike is not an issue as you can find a gas station on almost every corner. But if you are planning on traveling in remote regions like deserts, jungles, or the Bolivian Altiplano, you had better take some extra fuel with you.

If you want to expand your fuel range, you can put some extra gas on your motorcycle in three different ways:

  • Strapping extra fuel cans on the bike
  • Replacing the stock fuel tank with a bigger one
  • Installing a second (known as “auxiliary”) fuel tank

Let’s take a closer look at each of these solutions.

Extra Fuel Cans

The easiest way to carry extra gas on you is to strap fuel cans on your motorcycle. Although this may work in emergency situations, it’s definitely not recommended in the long run. This is because strapping down the can on the bike is rather difficult and a small mistake can result in a dangerous situation.

Therefore, if you are looking for a more convenient and safer solution, you should consider stackable motorcycle gas cans.

These cans can typically be attached to the rear racks and give you 1-4 gallons of extra gas per can. You can even mount up to two of them on either side of the machine.

Oversized Motorcycle Tanks

If you are looking for the safest way to increase your motorcycle’s fuel capacity, you may want to install an oversized tank on your bike.

These aftermarket tanks are available for many touring and adventure motorcycles and can even reach a fuel capacity of 10-11 gallons. These oversized motorcycle tanks can be really useful, but unfortunately they make your bike pretty heavy.

The trick here is that you don’t need to top off this tank if it’s not absolutely necessary. If you know that you can easily find gas stations on your way, you should have enough if you just fill it with 5-6 gallons.

Oversized tanks are often used on dirt bikes as well. Since the stock fuel tank on dirt bikes can only hold 1.5-2 gallons, it’s hard to cover longer distances on them.

This is where special oversized tanks come in handy. Some of them fit in with the design of the bike, while others are transparent to show how much gas is left.

Auxiliary Motorcycle Fuel Tanks

Another great way to increase a bike’s fuel capacity is to install an auxiliary motorcycle fuel tank. These extra tanks are typically connected to the fuel line and you can switch them on and off by turning a tap. Auxiliary tanks on motorcycles can hold about 1-5 gallons of gas.
