Why an Auxiliary Gas Tank for My Motorcycle Is Necessary

From my experience, having an auxiliary gas tank on my motorcycle has been a total game-changer. There have been times when I’ve been far from any gas stations, especially on long rides through remote areas. With the extra tank, I no longer worry about running out of fuel and getting stranded. It gives me peace of mind knowing I have that backup supply.

Another reason I find it necessary is the convenience during long trips. Instead of constantly stopping for fuel, the auxiliary tank extends my riding range significantly. This means fewer interruptions and more time enjoying the open road. It also helps when I’m riding with a group and want to keep pace without worrying about frequent refueling breaks.

Lastly, the auxiliary gas tank adds flexibility to my riding adventures. Whether I’m exploring off-road trails or heading out on a cross-country journey, having extra fuel capacity means I can plan routes that might otherwise be too risky. Overall, it’s an investment that enhances my freedom and confidence whenever I’m out on my bike.

My Buying Guides on ‘Auxiliary Gas Tank Motorcycle’

When I first started looking into auxiliary gas tanks for my motorcycle, I quickly realized there are several important factors to consider. To help you make a confident and informed decision, I’ve put together this guide based on my own experience and research.

Why I Needed an Auxiliary Gas Tank

For me, the primary reason was extending my riding range without frequent stops. Whether on long road trips or remote rides, having extra fuel capacity gave me peace of mind and greater freedom. If you ride in similar situations, an auxiliary gas tank can be a game-changer.

Types of Auxiliary Gas Tanks

I found there are mainly two types to consider:

  • Saddlebag or Pannier Tanks: These attach to the sides of your motorcycle, often replacing or complementing existing saddlebags. They offer decent capacity and keep the weight balanced.
  • Rear-mounted or Under-seat Tanks: These are compact and usually mounted behind the seat or under the tail section. They’re less visible and can be easier to install on some models.

Choosing the right type depends on your bike’s design and your personal preferences for capacity versus convenience.

Capacity and Size

One of the first things I checked was the tank capacity. Auxiliary tanks typically range from about 1 to 5 gallons. I wanted enough fuel to cover long distances but without adding too much bulk or weight. Think about how far you usually ride and how often you want to refuel when deciding on size.

Material and Durability

I paid close attention to the tank material. Common options include aluminum, steel, and high-grade plastic. Aluminum tanks are lightweight and rust-resistant, which worked well for me. Steel tanks are durable but heavier. Plastic tanks can be lighter and less expensive but may not be as rugged for off-road use.

Compatibility with My Motorcycle

Not all auxiliary tanks fit every motorcycle. I made sure to check compatibility with my bike’s make and model. Some tanks require specific mounting kits or modifications. I recommend looking for tanks specifically designed for your bike or universal options with adjustable mounts.

Installation Process

Installation complexity varies. Some tanks bolt on easily with included hardware, while others need professional installation or fuel line adjustments. Since I’m not a mechanic, I looked for tanks with clear instructions and good customer support.

Fuel Transfer Method

Consider how the fuel moves from the auxiliary tank to your main tank. Options include:

  • Manual transfer: Using a valve or pump to move fuel manually.
  • Automatic transfer: Tanks that connect to your fuel system and feed fuel automatically.

I preferred an automatic system for convenience, but manual tanks can be simpler and less expensive.

Price and Warranty

Prices vary widely based on capacity, material, and brand. I set a budget but also prioritized quality and warranty coverage. A good warranty gives me confidence in the product’s durability over time.

Additional Features to Look For

Some tanks come with extra features like fuel level gauges, locking caps, or integrated storage compartments. These little extras made a difference in my overall satisfaction.

My Final Tips

  • Always read user reviews and watch installation videos before buying.
  • Consider your riding style and terrain—off-road riders may need tougher tanks.
  • Don’t overlook weight distribution; an unbalanced tank can affect handling.
  • If unsure, consult with your motorcycle dealer or a professional mechanic.

I hope my buying guide helps you find the perfect auxiliary gas tank for your motorcycle, making your rides longer and more enjoyable!
