My Buying Guide to Motorcycle Auxiliary Fuel Tanks

Why I Chose to Get an Auxiliary Fuel Tank

When I started going on longer rides, I realized my motorcycle’s stock fuel tank just wasn’t enough. Running out of fuel in the middle of nowhere is frustrating and unsafe. An auxiliary fuel tank extends my range and gives me peace of mind on those long trips.

Understanding Different Types of Auxiliary Fuel Tanks

I learned there are several types of auxiliary tanks—portable, permanently mounted, and under-seat options. Portable tanks are convenient for occasional use and easy to carry. Permanently mounted tanks integrate well with the bike but require some installation effort. Under-seat tanks maintain a sleek look but usually have less capacity. Knowing these types helped me pick what fits my riding style.

Considering Capacity and Size

I had to balance how much extra fuel I wanted with the added weight and bulk. Larger tanks mean fewer stops but can affect handling. Smaller tanks are lighter but may not provide the range I need. I recommend measuring the space available on your bike and thinking about your typical ride length.

Material and Durability

I looked for tanks made from materials that resist corrosion and can handle rough conditions. Steel tanks are sturdy but heavier, while aluminum or plastic tanks are lighter but need to be well-made to avoid damage. Durability matters because I want the tank to last through all kinds of weather and terrain.

Installation and Compatibility

Before buying, I checked if the tank fits my motorcycle model and how easy it is to install. Some tanks come with mounting kits, while others might require custom work. I made sure the tank’s fuel lines and connections match my bike’s system to avoid leaks or malfunctions.

Fuel Delivery System

I paid attention to how the auxiliary tank feeds fuel into the main tank or engine. Some tanks use gravity feed, others have pumps or manual switches. I chose a system that’s reliable and simple to operate while riding.

Safety Features

Safety was a top priority for me. I looked for tanks with secure caps, proper venting, and leak-proof design. A good auxiliary tank should prevent spills and reduce fire hazards.

Budget and Value

I set a budget but kept in mind that quality and reliability are worth the investment. Cheaper tanks might save money upfront but could cause problems later. I weighed cost against features, durability, and ease of use.

My Final Tips

• Always double-check compatibility with your motorcycle.
• Consider how often and how far you ride.
• Think about installation—whether you can do it yourself or need a professional.
• Prioritize safety and durability over looks.

With these points, I found an auxiliary fuel tank that perfectly suits my riding needs and keeps me going farther with confidence.
