Fuel Tank Capacity: How To Choose The Right Bike

which bike has more fuel tank capacity

When it comes to motorcycles, fuel tank capacity and range are important considerations for buyers. While some buyers may not be concerned with tank range, it can be a deal-breaker for long-distance users or day-to-day commuters. This is because higher fuel tank capacity means fewer refuelling stops, which translates to extended riding range, improved rider comfort, and reduced costs. Various factors influence a bike's range, including fuel tank capacity, fuel consumption, engine size, and riding conditions.

Fuel efficiency vs. tank capacity

When it comes to two-wheelers, fuel efficiency and tank capacity are two critical factors that determine the riding range of a bike. While fuel efficiency refers to how far a bike can go on a unit of fuel, tank capacity is the maximum amount of fuel that the bike's tank can hold. Both these factors are essential considerations for riders, especially those who undertake long-distance trips or daily commutes.

The fuel efficiency of a bike is influenced by several factors, including engine displacement, vehicle weight, aerodynamic drag, driving habits, road conditions, and the efficiency of the transmission system. A more fuel-efficient bike will typically be able to travel a greater distance on the same amount of fuel compared to a less fuel-efficient bike. For example, the Yamaha FZ-S Fi 2.0, with its fuel-efficient 149cc engine, can achieve a range of 696 km on a single tank with a capacity of 12 litres. On the other hand, the Bajaj Avenger Street 150, with a slightly larger 14-litre tank, has a slightly lower fuel efficiency of 49.8 kmpl, resulting in a range of 697 km.

Tank capacity, on the other hand, refers to the maximum amount of fuel that a bike's tank can hold. A larger tank capacity means that the bike can carry more fuel, which can be advantageous for riders who want to travel longer distances without refuelling. For instance, the Mahindra Mojo has a massive 21-litre fuel tank and good fuel efficiency of 36.25 kmpl, resulting in a riding range of 761 km. Similarly, the Hero bike has a 13-litre fuel tank and impressive fuel efficiency of 58.7 kmpl, allowing it to go 763 km on a single tank.

However, it is important to note that while a larger tank capacity can provide greater range, it also adds weight to the bike, which can affect its performance and handling, especially on dirt roads. Additionally, the cost of a bigger tank versus the increase in capacity should also be considered, as it may not always be a financially viable option. In such cases, riders might opt for temporary solutions, such as carrying extra fuel containers or using collapsible or disposable containers.

Ultimately, the decision between fuel efficiency and tank capacity depends on individual needs and riding habits. For those who prioritize range and are willing to compromise on weight and cost, a larger tank capacity might be preferable. On the other hand, riders who value performance, handling, and fuel economy might opt for a more fuel-efficient bike with a smaller tank.

The pros and cons of bigger tanks

When it comes to motorcycles, fuel tank capacity is an important consideration, especially for those undertaking long-distance journeys or commuting. While some riders opt for fuel-efficient engines, others prefer larger fuel tanks to extend their range. This decision involves weighing the advantages and disadvantages of bigger tanks.

Advantages of Bigger Tanks:

  • Extended Range: The primary benefit of a larger fuel tank is increased mileage per tank. This is advantageous for long-distance trips, reducing the need for frequent refuelling stops. It offers convenience and peace of mind, especially when travelling in remote areas with limited access to fuel stations.
  • Reduced Refuelling Frequency: Bigger tanks allow riders to cover longer distances without worrying about refuelling. This can be a significant advantage for those who enjoy touring or adventure motorcycling, as it minimises interruptions during their journey.

Disadvantages of Bigger Tanks:

  • Increased Weight: Larger fuel tanks contribute to the overall weight of the motorcycle. This added weight can affect the bike's handling, particularly on smaller models or when riding on uneven terrain, such as dirt trails.
  • Bulk and Size: Bigger tanks can be bulkier, impacting the overall size and aesthetics of the motorcycle. This increased bulk may be a concern for those with limited storage space or those who prefer a sleeker, more compact design.
  • Cost: Upgrading to a larger fuel tank or modifying an existing one can be expensive. The cost of a bigger tank may outweigh the benefits, especially for those who primarily use their motorcycles for shorter commutes or leisure rides.
  • Handling and Ergonomics: The additional weight and size of a larger fuel tank can affect the handling dynamics of the motorcycle. It may require adjustments to the suspension or other components to accommodate the extra weight, impacting the overall riding experience and comfort.

Ultimately, the decision to opt for a bigger fuel tank depends on individual riding needs and preferences. While a larger tank offers the convenience of extended range, it may not be necessary for all riders, especially those who prioritise agility, cost, or the physical dimensions of their motorcycle.

How to increase fuel capacity

Increasing the fuel capacity of a motorcycle is a common consideration for long-distance riders or commuters. There are several ways to increase the fuel capacity of a motorcycle, each with its own advantages and disadvantages.

One option is to install an aftermarket tank with a larger capacity. This is a straightforward solution, but it can be costly and may require fabrication work. Another option is to enlarge the original equipment (OE) tank or fabricate a bigger one, but this will likely be an expensive undertaking. Carrying or mounting extra fuel containers is a more flexible approach, as it allows you to adjust the amount of extra fuel you need for different trips. Rigid containers, such as plastic cans, are generally easier to handle and secure than bags filled with fuel. Additionally, you can consider disposable or temporary containers for shorter trips.

If you're looking for a creative solution, you could try something like a hollow plastic dummy that sits behind you on the bike. You can fill it with gasoline and pump fuel directly into your tank as needed. Alternatively, you can add a fuel cell to your existing tank, but this option can also be costly.

While increasing fuel capacity is one way to extend your range, it's also important to consider improving fuel efficiency. Regular maintenance and servicing of your motorcycle are crucial for optimizing fuel efficiency. This includes tasks such as re-tuning the carburetor, maintaining proper tire pressure, and using high-quality, manufacturer-recommended fuel. Smooth acceleration, steady speeds, and anticipating stops can also help conserve fuel. Additionally, parking your bike in a shady area can prevent fuel loss due to evaporation and protect your paint from deterioration caused by direct sunlight.

How to calculate range

The range of a bike is determined by two key factors: the fuel tank capacity and the fuel efficiency of the bike. The fuel tank capacity is a simple, fixed measure of how much fuel the bike can hold. The fuel efficiency of the bike, often measured in miles per gallon (mpg) or kilometres per litre (kmpl), indicates how far the bike can travel on a certain amount of fuel.

To calculate the range of a bike, you can multiply the fuel tank capacity by the fuel efficiency. For example, the Yamaha FZ-S Fi 2.0 has a fuel tank capacity of 12 litres and a fuel efficiency of 58kmpl, resulting in a range of 696km (58kmpl x 12 litres = 696km).

It is important to note that the actual range achieved may vary due to various factors such as riding conditions, terrain, speed, and riding behaviour. For instance, riding with low fuel can cause the bike to consume more fuel to maintain its speed, reducing the overall range. Similarly, riding on dirt or off-road conditions may impact the range due to the increased fuel consumption associated with riding on uneven surfaces.

Additionally, the accuracy of manufacturer-claimed fuel efficiency figures is often questionable, as real-world conditions may differ from controlled testing environments. Independent surveys and reviews can provide more realistic fuel efficiency data, helping buyers make informed decisions about the expected range of a bike.

For electric bikes (e-bikes), the range calculation may be more complex due to the involvement of battery capacity, motor size, terrain, and pedalling effort. Several online e-bike range calculators are available, such as the Bosch eBike distance calculator and the RGE Electric Bike Range Calculator, which take into account various specifications and riding conditions to provide more precise range estimates.
