Best Gas Tank For Motorcycle: Compare Fit, Capacity, and Style

#1 · Best Overall

1. TOFR Sportster Tank

• Capacity: 16 liters
• Material: Iron
• Compatible with Vehicle Type: Street Cruiser Motorcycle
• Weight: 16 lb

Best for: Sportster extended-range replacement.

Why it ranks #1: Its 4.2-gallon capacity and listed fitment for 2007–2022 Sportster XL 883 and 1200 models make it a strong model-specific replacement choice.

A 4.2-gallon capacity is the main advantage of this TOFR tank for listed 2007–2022 Harley Sportster XL 883 and 1200 models, giving riders a larger fuel supply for longer stretches between stops. The listing also includes a cap and describes straightforward home installation, though handlebar-mounted speedometer position can affect the setup.

The 16-liter capacity provides a larger tank volume for riders seeking extended range, and the stated fitment covers Harley Sportster XL 883 and 1200 models from 2007–2022. A tank cap is listed as included, while the product description presents installation as straightforward and requiring no professional tools. One installation detail matters: a speedometer currently mounted low may need relocation to the upper position. The listing also notes an upper-clamp change may be needed for 883L/X48 models.

Skip it if you want a compact 1.5-gallon Ironhead tank; Tuningsworld’s 1955–1978 Sportster Ironhead Bobber tank is sized for that build.

This fits riders seeking more capacity on a listed 2007–2022 Sportster XL 883 or 1200. Check the speedometer position and, for an 883L or X48, the stated upper-clamp note before planning installation.

#2 · Highest Capacity

2. SLMOTO Stretched Tank

• Capacity: 4.7 gallons
• Material: Alloy Steel
• Compatible with Vehicle Type: Harley Custom Chopper, Harley Custom Bobber

Best for: Longer-range custom Harley builds.

Why it ranks #2: The 4.7-gallon capacity leads this selection, and its painted steel tank is listed for Harley custom chopper and bobber applications.

A 4.7-gallon capacity is the defining draw of this SLMOTO tank, giving Harley Custom Chopper and Bobber builders more fuel capacity than compact custom tanks. Its painted-black, heavy-duty 16-gauge steel construction arrives with a finished appearance, making it a practical option for a build planned around that style and size.

The 4.7-gallon capacity gives this tank a larger fuel volume for riders seeking fewer refueling stops, while the painted-black finish provides a ready-made appearance rather than a raw surface to customize. Its heavy-duty 16-gauge alloy steel construction specifies the material and gauge. The stated applications are Harley Custom Chopper and Bobber builds, but the listing calls it a custom tank and directs buyers to check the pictured dimensions before purchase.

Skip it if you need a stated set of tank dimensions before evaluating space; maXpeedingrods’ 1.5-gallon Sportster tank lists exact dimensions.

This suits a Harley custom Chopper or Bobber builder seeking 4.7 gallons and a black painted finish. Its size is presented in pictures, so the pictured measurements are a key boundary when planning the frame layout.

#3 · Honda Fitment

3. TCMT Honda Tank

• Capacity: 2.4 gallons
• Material: Iron
• Compatible with Vehicle Type: Motorcycle

Best for: Unpainted Honda retro builds.

Why it ranks #3: Its 2.4-gallon iron tank lists fitment for several Honda CD, CG, and GL models, with a bare finish ready for customization.

A 9-liter capacity gives this TCMT tank more room than many compact retro replacements, while its unpainted iron surface leaves the finish open to customization. The listed fitment includes several Honda CD, CG, and GL models, making it a candidate for riders restoring or reshaping those specific older motorcycle styles.

The 9-liter (2.4-gallon) capacity provides a relatively generous fuel volume for a retro custom project, and the thick iron construction is described as durable. Its unpainted surface lets the owner choose a paint design, while the listing also describes a baked-paint surface treatment, so the finish information should be read alongside the bare-steel designation. Fitment names Honda CD125, CG125, GL145, and GL125 year ranges, with additional models noted in the listing.

Skip it if you need stated dimensions to assess frame clearance; maXpeedingrods’ 1.5-gallon Ironhead tank lists its measurements.

Consider this for a Honda retro custom build within the listed CD, CG, or GL applications when 9 liters and a customizable finish appeal. Its unspecified dimensions make frame-space planning a key limitation.

#4 · Cafe Racer Style

4. DKMOTORK Cafe Racer Tank

• Capacity: 2.9 gallons
• Material: raw steel
• Compatible with Vehicle Type: Motorcycle
• Weight: 6.6 lb

Best for: Cafe racer frame modifiers.

Why it ranks #4: This 2.9-gallon raw-steel tank targets cafe racer builds and includes a cap and tap, but its listing warns that frame modification is required.

The listed 2.9-gallon capacity and raw-steel cafe-racer shape make this DKMOTORK tank a candidate for Honda, Yamaha, Suzuki, or Kawasaki customization. Its stated compatibility includes CG125 and YBR125, but the title flags that frame modification is required, making it most relevant to builders prepared to adapt the mounting setup.

Raw steel gives this tank a customizable surface for a cafe-racer project, while its 22.05 x 12 x 10.24-inch dimensions help builders compare its footprint with available frame space. The 2.9-gallon capacity offers a middle ground between compact custom tanks and larger options. The package listing includes a cap and tap, and the title explicitly requires frame modification, so installation involves adapting the motorcycle rather than assuming a direct fit.

Skip it if you need a tank explicitly listed for your Harley Sportster without frame modification; TOFR lists 2007–2022 Sportster XL 883 and 1200 fitment.

Pick this for a cafe-racer conversion where raw steel, 2.9 gallons, and the supplied cap and tap suit the plan. It is a poor match for a straightforward swap, since frame modification is required.

#5 · Included Hardware

5. 4into1 Pup Tank

• Capacity: 7 liters
• Material: Alloy Steel
• Compatible with Vehicle Type: Motorcycle
• Weight: 4.8 lb

Best for: Classic bobber and chopper builds.

Why it ranks #5: The 1.8-gallon black bobber-style tank includes a locking cap with keys and a petcock, though frame modification may be needed.

A classic black bobber profile and 1.8-gallon capacity give The Pup a clear role in custom chopper, bobber, or mini-bike projects. Its locking gas cap with keys and petcock for 3/16-inch fuel line add practical fuel-system details, while the listing warns that frame modification may be required to mount it.

The 1.8-gallon (7-liter) capacity suits a custom build seeking more than a very small tank, and the black finish supplies a classic appearance. A locking cap with keys is included, and the petcock is specified for 3/16-inch fuel line, helping buyers plan the fuel connection. The listing directs buyers to dimensions in the photos and warns that motorcycle-frame modification may be needed, so mounting should be assessed before installation.

Skip it if you need a tank with stated Harley Sportster year fitment and no listed frame-modification caveat; TOFR lists 2007–2022 Sportster XL 883 and 1200 models.

Choose The Pup for a black classic-style bobber, chopper, or mini-bike project needing 1.8 gallons and its included locking cap and petcock. Review the pictured dimensions and allow for possible frame modification.

#6

6. Tuningsworld Ironhead Tank

• Capacity: 5 liters
• Material: Iron
• Compatible with Vehicle Type: Motorcycle
• Weight: 2200 g

Best for: Raw-steel Ironhead customizers.

Why it ranks #6: Its 1.5-gallon raw-steel tank is listed for Harley Sportster Ironhead Bobber models from 1955–1978 and can be customized.

Bare raw steel gives this 1.5-gallon Tuningsworld tank a finish you can paint, polish, or personalize, while its stated fitment targets Harley Sportster Ironhead Bobber models from 1955–1978. Its compact capacity and custom-ready surface suit riders shaping a classic build around their own visual choices.

The 5-liter capacity keeps this tank in a compact format for a classic motorcycle project, while its 17.32 x 9.84 x 8.66-inch dimensions provide concrete measurements for assessing the space available on a frame. Iron construction supplies the tank material, and the unpainted raw-steel surface leaves finishing choices to the builder. The listing gives 1955–1978 Sportster Ironhead Bobber fitment; its additional guidance says to compare the tank’s bottom size with the frame when considering other years.

Skip it if you need a larger tank than 1.5 gallons; SLMOTO’s 4.7-gallon Harley Custom Chopper Bobber tank offers more capacity.

Choose this for a Harley Ironhead Bobber project where a small 1.5-gallon tank and a personally finished raw-steel surface suit the build. The listed dimensions and frame-bottom check matter when assessing mounting space.

#7

7. maXpeedingrods Ironhead Tank

• Capacity: 1.5 gallons
• Material: Iron
• Compatible with Vehicle Type: Motorcycle

Best for: Personalized Ironhead bobbers.

Why it ranks #7: This 1.5-gallon unpainted iron tank lists the same 1955–1978 Harley Sportster Ironhead Bobber fitment, with dimensions provided for checking.

An unpainted 1.5-gallon tank gives maXpeedingrods’ Ironhead Bobber option a blank surface for custom artwork, while the listing targets Harley Sportster Ironhead Bobber models from 1955–1978. Its stated dimensions also let builders compare the tank’s footprint with their frame before committing to this compact custom-build format.

The 1.5-gallon (5-liter) capacity keeps the tank compact for a custom Ironhead project, and its 17.32 x 9.84 x 8.66-inch measurements help assess available frame space. The raw, unpainted iron surface lets the owner apply a personal design rather than accept a preset painted finish. Fitment is listed for 1955–1978 Harley Sportster Ironhead Bobbers; the supplied guidance also recommends checking the tank’s bottom size against the frame for other years.

Skip it if you want a painted tank ready to install without planning a custom finish; SLMOTO’s black 4.7-gallon Harley custom tank has a painted surface.

Choose this for a compact Ironhead Bobber build where custom artwork and the listed 1.5-gallon capacity are priorities. Its raw finish and frame dimensions make finishing and mounting-space assessment part of the project.

8. FVRITO Motorized Bike Tank

• Capacity: 1.06 gallons
• Material: Metal
• Compatible with Vehicle Type: Bike
• Weight: 1.53 kg

Best for: Motorized-bike fuel-system kits.

Why it ranks #8: Its 4-liter metal tank suits 49–80cc two-stroke motorized bicycles, not a typical motorcycle, which limits its relevance to this search.

The FVRITO 4-liter metal tank lists a broad set of supplied fuel-system parts—cap, spark plug, petcock, fuel line, and filter—alongside compatibility with 49cc, 60cc, 66cc, and 80cc two-stroke engines. That combination suits motorized-bike projects where matching the tank with basic fuel-feed components is useful.

A 4-liter (1.06-gallon) capacity supports the listing’s goal of longer motorized-bike journeys, while the specified engine range helps buyers check whether the tank suits their two-stroke setup. The listed cap, petcock, fuel line, and filter group several fuel-system components with the metal tank, reducing separate component sourcing. Compatibility also covers ordinary, mountain, and road bicycles, plus touring bikes and modified mini-bike replacements as described.

Skip it if you want a tank whose details specify a mounting method; TIMZH’s 4-liter two-stroke tank also leaves that information unstated, so choose a listing with dimensions instead.

This suits a 49cc–80cc two-stroke motorized-bike project where a 4-liter tank and the listed fuel-system parts are useful. The supplied information does not give dimensions, so frame clearance remains an open fit consideration.

#9

9. TIMZH Motorized Bike Tank

• Capacity: 4 liters
• Material: Metal
• Compatible with Vehicle Type: Bicycle, Motorized Bike
• Weight: 1.8 kg

Best for: Two-stroke motorized-bike riders.

Why it ranks #9: This 4-liter tank is specified for 49–80cc two-stroke engines and bicycles, making it less suitable for buyers seeking a motorcycle tank.

Compatibility with 49cc, 60cc, 66cc, and 80cc two-stroke engines sets this 4-liter TIMZH tank apart from motorcycle-only custom tanks. It is also listed for ordinary, mountain, road, and touring bicycles, making it relevant to motorized-bike conversions that need a tank sized for those engine classes.

The 4-liter capacity is presented as support for longer cycling trips, while the listed 49cc through 80cc two-stroke compatibility helps narrow its intended engine applications. Its metal construction supplies a defined material for a motorized-bike installation. The description names ordinary bicycles as well as mountain, road, and touring bikes, so buyers can assess it for several bicycle formats, though the supplied information does not state tank dimensions or a particular mounting method.

Skip it if you need a stated package of cap, petcock, filter, and fuel line; FVRITO’s 4L motorized-bike tank lists those components.

This suits a motorized-bike owner whose engine is among the listed 49cc–80cc two-stroke sizes and who wants 4 liters of capacity. The available details leave dimensions and mounting method unspecified.
