Best Gas Tank For Motorcycle: Compare 10 Replacement Tanks

#1 · Best Overall

1. XMT-MOTO Honda Tank

• Capacity: 2.4 gallons
• Material: Alloy Steel
• Compatible with Vehicle Type: Motorcycle

Best for: Honda replacements with included cap.

Why it ranks #1: Its 2.4-gallon capacity fits listed Honda CD, CG, and GL models, and the package includes a fuel cap, two keys, and a switch.

A 2.4-gallon alloy-steel tank supplied with a cap and two keys gives owners of listed Honda CD, CG, GL and related models a replacement starting point. The stated core fitment includes several specific year ranges, while other named Honda applications require custom mounting work.

The listed CD125, CG125, GL145 and GL125 years help buyers check the tank against a specific Honda model, and the 2.4-gallon capacity supports fuel-volume planning. Alloy-steel construction identifies the material, while the included cap and two keys provide components for the replacement workflow. XL175, XL250, CL350 and CB-series applications require welded, newly created mounting positions, so those uses involve fabrication and a check of tank size.

Skip it if you need a direct-fit Harley Sportster tank with 4.2 gallons; the TOFR 2007–2022 XL 883/1200 tank lists that use.

Honda CD125, CG125, GL145 and GL125 owners seeking a 2.4-gallon tank with cap and keys have the most specific fitment guidance here. For the additional XL and CB applications, plan for welding and verify frame dimensions.

#2 · Best Bare Steel

2. TCMT Honda Tank

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

Best for: Unpainted Honda cafe-racer builds.

Why it ranks #2: This 2.4-gallon iron tank lists the same Honda CD, CG, and GL fitments and has an unpainted finish for a custom paint scheme.

A 2.4-gallon unpainted iron tank gives Honda CD, CG and GL custom-build owners a base they can finish to suit a cafe racer or scrambler. The stated model-year ranges cover several Honda variants, while the retro appearance and thick iron construction define its look and material.

The listed CD125, CG125, GL145 and GL125 year ranges help owners identify a direct application to investigate, and the 2.4-gallon capacity supplies a concrete volume for planning. Its unpainted finish leaves room for a chosen paint design, while the iron construction and retro appearance fit the stated custom aesthetic. The listing also names XL175, XL250, CL350 and CB models, but those applications require welding and fabricated mounting positions.

Skip it if you need a larger 4.2-gallon Harley Sportster tank; the TOFR XL 883/1200 tank lists that capacity and application.

Honda owners seeking an unpainted 2.4-gallon tank for a listed CD, CG or GL model can use its fitment ranges as a starting point. Other named Honda models need fabrication, so confirm frame and mounting requirements for those builds.

#3

3. SLMOTO Honda Tank

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

Best for: Honda restoration and custom builders.

Why it ranks #3: Its 2.4-gallon iron tank lists Honda CD125, CG125, GL145, and GL125 fitments, with a cap, two keys, and a switch included.

A 2.4-gallon iron tank with listed Honda CD125, CG125, GL145 and GL125 applications gives owners of those models a defined starting point for a replacement or custom build. The listing also names several larger Honda models, but those require fabricated mounting positions rather than a direct fit.

The stated year ranges cover CD125, CG125, GL145 and GL125 versions, helping owners narrow compatibility before planning a swap. Its 2.4-gallon capacity provides a concrete fuel-volume reference for a build, while the iron construction identifies the tank material. For XL175, XL250, CL350, CB350, CB450, CB550, CB650 and CB750 applications, the listing requires welding and creating suitable mounting positions, so installation involves fabrication and checking tank dimensions against the frame.

Skip it if you need a direct-fit tank for an XL175 or CB-series Honda; the TOFR Sportster tank targets Harley Sportsters instead.

Honda CD125, CG125, GL145 and GL125 owners seeking a 2.4-gallon iron replacement have the clearest application match here. Custom builders considering the other listed Honda models should be prepared to weld mounts and verify tank dimensions.

#4 · Largest Capacity

4. TOFR Sportster Tank

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

Best for: Longer-range Sportster replacement.

Why it ranks #4: The 4.2-gallon tank offers the largest listed capacity here and fits 2007–2022 Sportster XL 883 and 1200 models, with a cap included.

The 4.2-gallon capacity is the defining feature of this TOFR tank, giving compatible Harley Sportster XL 883 and 1200 riders more fuel volume between fill-ups. Its listed 2007–2022 fitment provides a specific model-year target, while included reducer shims address multiple handlebar clamp sizes.

TOFR lists fitment for 2007–2022 Sportster XL 883 and 1200 models and describes installation as straightforward without professional tools, supporting a home replacement workflow. The 16-liter capacity enables longer intervals between refueling according to the listing. Reducer shims adapt the original 1-1/4-inch clamp for 1-inch and 1-1/8-inch handlebars; however, a lower-mounted speedometer may need relocation, and 883L/X48 models may need a different upper clamp.

Skip it if you ride a Honda CD125 or GL125 and need its listed tank fitment; the TCMT 2.4-gallon Honda tank targets those models.

Sportster XL 883 and 1200 owners prioritizing fewer fuel stops can consider this larger-capacity option, especially when its clamp shims match their bars. Check speedometer position and the 883L/X48 upper-clamp note before planning installation.

#5 · Heavy-Duty Steel

5. Biker's Choice Flatside Tank

• Capacity: 3.5 gallons
• Compatible with Vehicle Type: Motorcycle

Best for: Steel flatside replacement seekers.

Why it ranks #5: Its 3.5-gallon heavy-duty steel construction and listed Harley FLST Heritage Softail fitment suit riders seeking a larger, model-specific replacement.

Heavy-duty steel construction anchors this Biker's Choice 3.5-gallon flatside tank, giving motorcycle owners a substantial metal option in a specified capacity. Its listed dimensions and 22mm threads offer practical planning details, while the requirement for a vented cap on the right side shapes the installation setup.

The 3.5-gallon capacity provides a larger stated volume than compact bobber tanks, and the 20-by-16-by-11.2-inch dimensions give a reference for checking space on the motorcycle. Heavy-duty steel and an OEM-replica description identify its construction and intended replacement character. It uses screw-in gas caps, which are not included, and a vented cap must be used on the right side; buyers need to source the cap and account for that arrangement.

Skip it if you need a tank with a supplied cap and keys; the XMT-MOTO 2.4-gallon Honda tank includes a cap and two keys.

This suits a buyer seeking a 3.5-gallon steel flatside tank and able to source the specified screw-in vented cap. Use its dimensions and application details to check the motorcycle's available space before committing to the replacement.

#6

6. MOTO IRON Frisco Tank

• Capacity: 2.5 gallons
• Material: Metal
• Compatible with Vehicle Type: Bike

Best for: Frisco-mount bobber builds.

Why it ranks #6: The 2.5-gallon Frisco-mount Sportster bobber tank offers more capacity than the small Ironhead options, though the supplied data gives limited fitment detail.

A 2.5-gallon capacity gives this MOTO IRON Frisco-mount Sportster bobber tank a clear role in a custom build where that stated format and volume suit the project. The supplied information identifies its capacity and metal construction, but does not provide model-year fitment details.

The 2.5-gallon figure helps a builder assess whether the tank's stated volume suits the intended riding setup, while the metal material establishes the basic construction. Its title identifies a Frisco-mount Sportster bobber format, which gives the product a defined custom-bike context. The supplied specifications do not list compatible years, dimensions, or included hardware, so builders cannot use this listing alone to confirm frame clearance or installation requirements.

Skip it if you need stated dimensions or year-by-year fitment; the maXpeedingrods 1.5-gallon tank lists measurements and Ironhead years.

A builder looking specifically for a 2.5-gallon Frisco-mount Sportster bobber tank may find the stated format and material useful. The limited fitment information makes it a poor choice when dimensions or exact model-year compatibility must be verified from the listing.

#7

7. Tuningsworld Ironhead Tank

• Capacity: 3.1 gallons
• Material: Iron
• Compatible with Vehicle Type: Motorcycle

Best for: Custom-finish Ironhead builders.

Why it ranks #7: This raw iron tank is listed for 1955–1978 Sportster Ironhead bobbers, but its feature text says 2.4 gallons while specifications list 3.1.

Bare raw steel is the defining appeal of this Tuningsworld tank, giving Harley Sportster Ironhead bobber builders a surface they can paint, polish or decorate. The title targets 1955–1978 models, and the specifications list 16.54-by-9.84-by-9.45-inch dimensions for frame-space planning.

The raw-steel finish makes personalization part of the build, while the listed dimensions help a buyer compare the tank with the frame before installation. The product title describes it as a 2.4-gallon tank, but its specification table lists 3.1 gallons, so the capacity information is inconsistent and should not be treated as settled. Its Ironhead bobber application is stated for 1955–1978; the supplied facts do not provide mounting hardware details.

Skip it if you require an unambiguous fuel capacity; the maXpeedingrods Ironhead tank lists a consistent 1.5-gallon figure.

This is for a classic Ironhead bobber builder who values a customizable raw-steel finish and can compare the listed dimensions with the frame. Resolve the conflicting capacity figures before relying on this tank for range planning.

#8

8. maXpeedingrods Ironhead Tank

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

Best for: Small raw-steel bobber projects.

Why it ranks #8: Its 1.5-gallon raw iron tank is listed for 1955–1978 Sportster Ironhead bobbers and can be customized, but provides less capacity.

An unpainted 1.5-gallon raw-steel tank lets Harley Sportster Ironhead bobber builders add their own graphics or finish while using a compact stated fuel capacity. The listing names 1955–1978 applications and provides dimensions, giving a project builder useful starting points for checking the frame and planning customization.

The 17.32-by-9.84-by-8.66-inch measurements let builders compare the tank's footprint with their frame, and the listing specifically advises checking the bottom size for attachment. Its unpainted iron surface can be decorated according to the buyer's preferences, making finish work part of the project rather than a fixed paint choice. The 1.5-gallon volume suits buyers who accept less fuel capacity than the listed 2.4-gallon Tuningsworld tank.

Skip it if you want more listed capacity for a classic Harley build; the Tuningsworld 2.4-gallon tank offers a larger stated volume.

Choose this for a compact Ironhead bobber project where custom paint or artwork and the stated dimensions suit the frame. Its 1.5-gallon capacity is the key boundary for riders who want longer intervals between refueling.

#9

9. NewYall Ironhead Tank

• Capacity: 1.5 gallons
• Material: Polymer/Plastic
• Compatible with Vehicle Type: Street Sport Motorcycle/Cruiser Motorcycle

Best for: Compact plastic Ironhead replacement.

Why it ranks #9: This 1.5-gallon tank lists 1955–1978 Sportster Ironhead bobbers, but its plastic material differs from the iron and metal alternatives.

Polymer construction distinguishes this NewYall 1.5-gallon tank from the metal options listed for Harley Sportster Ironhead bobbers. Its stated 1955–1978 application and compact fuel volume give classic-bike owners a clear target, with a different material choice for a street sport or cruiser motorcycle.

The 1.5-gallon capacity gives buyers a defined, compact volume for an Ironhead bobber setup, and the listing names 1955–1978 Harley Sportster Ironhead models as its application. Polymer/plastic material is the key construction distinction, so it suits shoppers specifically seeking that material rather than an iron tank. The supplied details do not include dimensions or mounting information, limiting how much frame fit can be assessed from the listing alone.

Skip it if you want a raw-steel tank with listed dimensions for a custom finish; the maXpeedingrods Ironhead tank provides both.

Consider this when a 1.5-gallon plastic tank is the material and volume you want for a listed Ironhead bobber application. Because dimensions and mounting details are absent from the supplied information, it offers limited fit-planning guidance.

#10

10. TIMZH Motorized Bike Tank

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

Best for: Two-stroke motorized bicycle riders.

Why it ranks #10: Its 4-liter metal tank fits 49cc–80cc two-stroke motorized bicycles, so its stated use is narrower than a conventional motorcycle replacement.

A 4-liter capacity gives this TIMZH metal tank a stated fuel volume for 49cc, 60cc, 66cc and 80cc two-stroke motorized-bike setups. Its listed compatibility spans ordinary, mountain, road and touring bicycles, making it a specialized option for riders converting or equipping those bicycle types.

The engine-size range helps a buyer identify whether this tank targets their two-stroke motorized-bike setup, while the stated bicycle categories broaden the intended bicycle formats. Four liters of capacity supports the listing's long-distance-use emphasis by providing a defined fuel volume for a ride. Metal construction is specified, and the included-components field identifies a gas fuel tank; the supplied information does not detail mounting dimensions or installation hardware.

Skip it if you need a motorcycle-specific Honda replacement with stated model years; the TCMT 2.4-gallon tank lists Honda CD, CG and GL fitment.

Motorized-bicycle owners with one of the listed two-stroke engine sizes can use the 4-liter capacity and broad bicycle categories to assess relevance. Check mounting needs independently, since dimensions and installation hardware are not detailed in the supplied facts.
