My Buying Guides on Best Auxiliary Fuel Tank For Motorcycle
When I first considered getting an auxiliary fuel tank for my motorcycle, I was overwhelmed by the options available. After doing my research and trying a few different models, I’ve compiled a guide to help you choose the best auxiliary fuel tank for your motorcycle. Here’s everything you need to know to make an informed decision.
Understanding Auxiliary Fuel Tanks
Before diving into specific models, it’s essential to understand what an auxiliary fuel tank is. For me, it’s a game changer that extends my riding range, especially on long trips where fuel stations are scarce. These tanks can be mounted on the bike, usually on the rear or sides, and allow you to carry additional fuel safely and conveniently.
Key Considerations
1. Capacity
When selecting an auxiliary fuel tank, capacity is one of the first things I consider. The size I choose depends on how far I plan to ride without refueling. I’ve found tanks that range from 1 to 5 gallons. For long-distance trips, I prefer a larger capacity to minimize stops.
2. Material
The material of the tank plays a significant role in durability and weight. My experience has shown that aluminum tanks are lightweight and corrosion-resistant, while steel tanks are heavier but often more rugged. I usually opt for aluminum because it balances weight and strength well.
3. Mounting Options
How the tank mounts to my motorcycle is crucial. I’ve seen tanks that can be mounted on the rear rack, side bags, or even integrated into the frame. I recommend choosing a tank that fits my motorcycle’s design and doesn’t interfere with my riding comfort.
4. Fuel Compatibility
Not all auxiliary tanks are suitable for all types of fuel. I always check if the tank is compatible with gasoline or diesel, depending on my motorcycle’s requirements. Most tanks I’ve encountered are designed for gasoline, but it’s wise to verify.
5. Safety Features
Safety is paramount when carrying extra fuel. I look for tanks with secure sealing mechanisms and built-in safety features like pressure relief valves. A good auxiliary tank should minimize the risk of leaks or spills.

- Gather Tools: Ensure you have all necessary tools on hand, including wrenches and mounting brackets.
- Test Fit: Before securing everything, I recommend doing a test fit to ensure it aligns well with my motorcycle.
- Check for Leaks: After installation, I always perform a leak test by filling the tank with a small amount of fuel and checking for any drips.
Maintenance Tips
To keep my auxiliary fuel tank in optimal condition, I follow these maintenance tips:
- Regular Inspections: I check for rust or leaks regularly, especially if the tank is made of steel.
- Cleanliness: Keeping the exterior clean helps prevent corrosion. I wipe it down after every ride.
- Fuel Quality: I always use fresh fuel to prevent gumming or clogging of the fuel system.
