Fuel tanks shape more than just your bike’s fuel range. They change the way your machine looks, feels, and carries its weight on the road. Whether you’re refreshing a worn-out stock tank or building something with a longer, stretched profile, the right setup makes a real difference in daily riding. At WyldPerformance, this collection is built for riders who want dependable fitment and performance-focused upgrades without the guesswork.
Inside this category, you’ll find a mix of stock-style replacements and stretched custom options designed for popular Harley platforms and V-twin builds. Capacities range from compact 2.4-gallon tanks to larger 4.2-gallon designs that help extend your riding distance. Smaller tanks keep the bike slim and responsive. Larger stretched tanks offer better fuel range while adding a stronger visual stance. Raw steel options are ideal for paint or full custom work, while direct-fit replacements make upgrades straightforward. Many tanks are EFI-compatible where noted, and dual-cap or single-cap styles give you the freedom to match your build’s look and function.
Performance isn’t only about horsepower. Tank shape affects rider position and control. A narrower profile improves knee grip and overall comfort. Added capacity reduces fuel stops on longer rides. Clean welds and solid mounting points help prevent vibration issues over time. The goal is simple — parts that fit right and ride right.
If you’re dialing in a custom build or replacing an aging tank, choose the style and capacity that matches how you ride. WyldPerformance focuses on quality parts riders can rely on — straightforward upgrades that improve range, refine the bike’s profile, and keep you focused on the road ahead.
Check the model years and fitment notes listed on each product page. Some tanks may require brackets, adapters, or specific hardware depending on your bike.
Stretched tanks usually offer more fuel capacity and a longer, custom look. They can also slightly change rider position and the bike’s overall balance.
Raw tanks are typically unfinished. They’re meant for paint, powder coat, or custom finishing before installation.
A bigger tank adds weight when full, but it also increases range. Many riders prefer the balance of fewer fuel stops on longer rides.
Some are, and some are not. Always check the product description to confirm EFI compatibility and required components.
In many cases, yes. However, it depends on the specific tank design. The product details will note if OEM parts transfer over.
