TOFR Black 4.2 Gallon Gas Tank
The TOFR tank is designed for long-range riding on Harley Sportster XL 883/1200 models from 2007 to 2022. It offers a notable 4.2-gallon capacity, significantly extending riding range and reducing refueling stops. The package includes a tank cap, simplifying installation for riders updating factory tanks. Consider mounting compatibility with existing fuel lines and the cowling of your Sportster to ensure a clean fit and clearance for the cap.
SLMOTO Unpainted 9L Tank
This universal tank provides a generous capacity and broad compatibility with multiple classics and customs. It arrives unpainted, giving builders freedom to customize color and finish. A key note: mounting positions must be crafted to fit the tank correctly on the intended frame, and verify that the size aligns with your bike’s geometry and tank mounting points. The package includes caps and an oil can switch for convenience.
Tuningsworld 1.5 Gal Tank
This 1.5-gallon tank targets Harley Sportster Ironhead Bobber builds from 1955–1978. It arrives in raw steel, enabling painters and metalworkers to achieve a personalized look that matches vintage aesthetics. The capacity is sized for daily riding or weekend cruises, but buyers should verify fit with their frame, seat height, and handlebars to avoid clearance issues or misalignment with mounting brackets.
Tuningsworld 2.4 Gal Tank
The 2.4-gallon variant suits Harley Sportster Ironhead Bobber builds from 1955–1978. As with other Tuningsworld tanks, it’s sold in raw steel to support customization. Confirm compatibility with your frame’s mounting points and ensure the tank’s length and width align with your seat and side panels to prevent interference with the fuel filler or side covers.
SLMOTO 4.7 Gallon Painted Tank
Designed for Harley Custom CHOPPER or BOBBER builds, this 4.7-gallon painted tank provides a substantial fuel capacity with a finished black look. It’s important to verify that the tank’s mounting points align with your frame’s brackets and that the additional capacity does not affect weight distribution or fuel line routing. The painted finish also reduces immediate customization work for riders seeking a quicker installation.
Buying Guide
Key purchase considerations when selecting a dished motorcycle gas tank for Harley and similar builds include:
- Capacity and range: Higher gallons extend riding distance but increase weight and potential fuel slosh. Match capacity to typical riding distances and riding style.
- Compatibility: Confirm model years, engine type, and frame compatibility. Some tanks require mounting brackets or frame modifications.
- Mounting and fit: Evaluate mounting position, under-seat clearance, and seat height with the tank installed. Unpainted tanks offer customization flexibility but may demand more prep work.
- Material and finish: Steel tanks (unpainted or painted) vary in weight and durability. Painted tanks provide a ready-to-install look; raw steel invites customization.
- Fittings and accessories: Check whether tanks include caps, petcocks, or mounting hardware. Some listings require you to source caps separately.
- Finish maintenance: Paint durability, rust resistance, and the need for sealants or coatings can influence long-term upkeep.
- Welding and fabrication: For universal tanks, welding and fabricating mounting brackets or adapters may be necessary for proper alignment and safety.
These tanks span classic and modern builds, offering options for restorations, restomods, and custom choppers or bobbers. When evaluating, compare the mounting hardware requirements, fuel capacity versus weight distribution, and how the tank integrates with existing fuel systems and styling goals.
