Why a Motorcycle Auxiliary Gas Tank is Necessary
As an avid motorcyclist, I’ve always valued the freedom that comes with hitting the open road. However, I quickly learned that long rides can sometimes be hindered by the limitations of a motorcycle’s fuel capacity. That’s where my auxiliary gas tank comes into play. Having that extra fuel reserve has transformed my riding experience, allowing me to venture further without the constant worry of running out of gas.
One of the main reasons I find the auxiliary gas tank indispensable is the convenience it offers during long trips. I often take extended journeys through remote areas where gas stations are few and far between. With an auxiliary tank, I can easily double my range, giving me the freedom to explore without being tethered to a fuel map. It’s reassuring to know that if I decide to take a detour to explore a scenic route, I won’t be left stranded in the middle of nowhere.
Additionally, the peace of mind that comes with having extra fuel is invaluable. I recall a ride where I was caught in unexpected traffic, and my fuel gauge was creeping toward empty. Instead of panicking, I simply tapped into my auxiliary tank, which allowed me to keep going without stress. It’s not just about
My Buying Guides on Motorcycle Auxiliary Gas Tank
When I first started riding long distances on my motorcycle, I quickly realized the importance of having extra fuel on hand. That’s when I discovered motorcycle auxiliary gas tanks. These handy devices have made my trips much more enjoyable and stress-free. Here’s my comprehensive buying guide to help you choose the right auxiliary gas tank for your needs.
Understanding Auxiliary Gas Tanks
Before diving into options, I want to clarify what an auxiliary gas tank is. Simply put, it’s an additional fuel storage container that can be mounted on your motorcycle. This extra capacity allows you to travel longer distances without worrying about running out of gas. I’ve found it particularly useful when riding through remote areas where gas stations are few and far between.
Types of Auxiliary Gas Tanks
In my experience, there are a few different types of auxiliary gas tanks available:
- Portable Tanks: These are typically smaller, easy to carry, and can be strapped to various parts of your bike. I’ve used these for short trips where I just need a little extra fuel.
- Hard-Mounted Tanks: These tanks are permanently mounted to your motorcycle and offer a more integrated solution. They tend to have larger capacities, which I prefer for long-distance rides.
- Fuel Bladders: These flexible tanks can be stored in your saddlebags or backpack. They’re lightweight and take up minimal space, making them a great option for my adventures.
Capacity Considerations
When I choose an auxiliary gas tank, capacity is a major factor. I generally look for tanks that hold at least 1 to 2 gallons of fuel. This amount has been sufficient for my needs, allowing me to extend my range without adding too much weight to my bike. It’s essential to balance the tank size with the weight and dimensions of my motorcycle.
Material and Durability
The material of the auxiliary gas tank is another critical aspect. I prefer tanks made from high-quality materials like aluminum or high-density polyethylene (HDPE). These materials are lightweight yet durable, making them resistant to corrosion and impact—two things that are vital for a motorcycle accessory.
Ease of Installation
I’ve had my share of struggles with complicated installations, so I always look for tanks that come with clear instructions and all necessary mounting hardware. Some tanks are designed for easy installation, allowing me to set them up quickly without any special tools. This is a huge plus for me, especially on road trips.
Safety Features
Safety is paramount for me when carrying additional fuel. I make sure the auxiliary gas tank has features like a secure cap, venting system, and proper sealing to prevent leaks. Tanks with built-in safety features give me peace of mind while on the road.
Price Range
Auxiliary gas tanks come in various price ranges. I’ve found that spending a little more on a reputable brand often pays off in terms of durability and performance. Prices typically range from $50 to $300, depending on capacity and material. I always recommend setting a budget but being open to investing in quality.
Brand Reputation
Over the years, I’ve learned to trust certain brands when it comes to motorcycle gear. Doing some research on the reputation of the brand can save you from future headaches. Reading reviews and seeking recommendations from fellow riders has helped me choose reliable options.
my experience with motorcycle auxiliary gas tanks has been overwhelmingly positive. They have enhanced my riding experiences by providing peace of mind and convenience. By considering the type, capacity, material, installation ease, safety features, price, and brand reputation, I’m confident you can find the perfect auxiliary gas tank for your motorcycle adventures. Happy riding!
