Why Motorcycle Auxiliary Fuel Tank is Necessary
From my experience, having an auxiliary fuel tank on my motorcycle has been a game-changer. One of the main reasons I find it necessary is the extended range it provides. When I’m out on long rides, especially through remote areas where gas stations are few and far between, the extra fuel gives me peace of mind. I don’t have to constantly worry about running out of gas or making frequent stops, which lets me focus more on enjoying the ride.
Another reason I appreciate the auxiliary tank is the convenience it adds. On trips where I’m carrying gear or traveling with friends, I’ve noticed how quickly the main tank can drain. The extra capacity means I can go farther without interruption. Plus, it’s saved me a couple of times when I miscalculated my fuel needs or took a longer detour. For me, this small addition has enhanced both my safety and freedom on the road.
My Buying Guides on Motorcycle Auxiliary Fuel Tank
When I first considered getting an auxiliary fuel tank for my motorcycle, I realized there’s a lot to think about before making the right choice. Here’s what I learned through my experience that might help you pick the best one for your needs.
Why I Needed an Auxiliary Fuel Tank
For me, the main reason was extending my riding range without frequent fuel stops. If you’re like me and enjoy long-distance rides or adventure touring, an extra fuel tank can be a game-changer. It gives you peace of mind when riding in remote areas with limited gas stations.
Types of Auxiliary Fuel Tanks
I found there are generally three types to consider:
- Saddle or Pannier Tanks: These attach to the sides of your bike, often replacing or supplementing panniers. They offer balanced weight distribution but may affect handling.
- Rear-mounted Tanks: Placed behind the seat or on the luggage rack. They’re easier to install but can shift your bike’s center of gravity.
- Tank Bags with Fuel Compartments: These combine storage and extra fuel but usually hold less fuel.
Choosing the type depends on your bike model and how much extra fuel you want to carry.
Capacity and Size Considerations
I had to think carefully about how many extra liters I wanted. Auxiliary tanks usually range from 2 to 10 liters or more. Bigger tanks mean fewer stops but add more weight and bulk. I balanced carrying enough fuel for my trips without compromising bike handling or storage space.
Material and Durability
I looked for tanks made from durable, lightweight materials like aluminum or high-grade plastic. Aluminum tanks tend to be more robust but heavier, while plastic tanks are lighter but may be less impact-resistant. Also, check if the tank is corrosion-resistant and has a good finish to withstand weather and road debris.
Installation and Compatibility
My bike’s make and model influenced which auxiliary tanks would fit best. Some tanks are universal, while others are designed specifically for certain motorcycles. I made sure the tank came with proper mounting hardware and clear instructions. If you’re not comfortable installing it yourself, consider professional help to ensure safety.
Fuel Delivery System
I paid attention to how the auxiliary tank feeds fuel into the main system. Some tanks connect directly via a fuel line with a valve or switch to control flow, while others require manual transfer. A seamless fuel delivery system that integrates well with your bike’s existing fuel setup is crucial to avoid running issues.
Safety Features
Safety was a top priority for me. I checked for tanks with secure caps to prevent leaks, proper venting to avoid pressure buildup, and certifications or approvals for fuel storage. Also, consider if the tank is designed to minimize fire hazards in case of accidents.
Price and Warranty
Prices vary widely based on capacity, material, and brand. I set a budget but was willing to invest a bit more for quality and reliability. Look for brands that offer warranties or customer support — it’s reassuring in case of defects or issues down the road.
Additional Tips from My Experience
- Test fit the tank on your bike before buying if possible.
- Read reviews from riders with similar motorcycles.
- Consider how often you’ll use the tank; for occasional long trips, a smaller or removable tank might be better.
- Keep in mind how the tank affects your bike’s weight distribution and handling, especially when full.
I hope my insights help you choose the right motorcycle auxiliary fuel tank that fits your riding style and needs!
