My Buying Guides on Best Auxiliary Fuel Tank For Motorcycle
When I first started looking for an auxiliary fuel tank for my motorcycle, I realized there were quite a few factors to consider to make the right choice. Here’s a guide based on my experience to help you find the best auxiliary fuel tank that fits your needs.
Why I Needed an Auxiliary Fuel Tank
Long rides and remote routes often left me worried about running out of fuel. My motorcycle’s stock tank just wasn’t enough for those extended trips. An auxiliary tank extended my range significantly, giving me peace of mind and the freedom to explore without constantly searching for gas stations.
Capacity and Size Considerations
One of the first things I looked at was how much extra fuel I wanted to carry. Auxiliary tanks come in various sizes, typically ranging from 1 to 5 gallons. I had to balance capacity with the added weight and bulk. Bigger tanks mean fewer stops but can affect handling and add weight. I chose a mid-sized tank that gave me around 2.5 gallons extra, which felt like a good compromise.
Material and Durability
Since the tank is exposed to heat, vibration, and sometimes rough terrain, I paid close attention to the material. Aluminum tanks are lightweight and durable, while steel tanks are sturdy but heavier. Some tanks use high-density plastic, which is lighter but might not be as durable in extreme conditions. I preferred an aluminum tank with a powder-coated finish for corrosion resistance.
Mounting System and Compatibility
I had to ensure the auxiliary tank could be securely mounted on my specific motorcycle model. Universal tanks are versatile but might require custom brackets or modifications. Some brands offer model-specific kits that simplify installation. I also checked if the tank came with mounting hardware or if I needed to buy it separately.
Fuel Delivery Method
There are two common methods: gravity feed and pump-assisted. Gravity feed tanks rely on height difference to supply fuel, which means the tank needs to be mounted higher than the carburetor or fuel injection system. Pump-assisted tanks have an electric or manual pump to transfer fuel, offering more flexible mounting options. I opted for a pump-assisted tank to avoid complicated positioning.
Ease of Installation and Use
I wanted a tank that was straightforward to install and operate. Some tanks come with quick-connect fittings and easy-to-use valves that make switching between the main and auxiliary tanks hassle-free. I also appreciated when the tank included clear fuel level indicators so I could monitor the remaining fuel at a glance.
Safety Features
Safety is paramount when dealing with fuel. I looked for tanks with secure, leak-proof caps and robust construction to prevent spills during rides. Venting systems are important to avoid pressure buildup. Additionally, I checked for certifications or compliance with safety standards.
Price and Warranty
Auxiliary fuel tanks come in a wide price range. I set a budget but was willing to spend a bit more for quality and reliability. A good warranty gave me confidence that the manufacturer stood behind their product, which was reassuring in case of defects or issues down the road.
Final Thoughts
Choosing the best auxiliary fuel tank for my motorcycle was about balancing capacity, material quality, ease of installation, and safety. By considering these factors, I found a tank that extended my riding range without compromising handling or safety. If you’re planning long rides or adventure touring, investing in a reliable auxiliary fuel tank can make a big difference in your journey.
I hope my buying guide helps you make an informed decision and enjoy your rides even more!
