Harley Davidson Motorcycle Gas Tanks

HARLEY-DAVIDSON GAS TANKS FOR CHOPPERS, BOBBERS AND CUSTOM BUILDS

The tank sets the visual proportion of the whole build. A peanut stretches the line and keeps the midsection open. A Frisco mount pushes the tank high on the backbone and changes the entire stance. A split Big Twin reads period-correct in a way nothing else does on a Panhead or Shovelhead. This collection covers every major Harley-Davidson tank profile for custom work: Frisco mount Sportster tanks, peanut and banana choppers, WX split Big Twin setups, Fat Bob configurations, and stock replacement tanks from Ironhead through EFI Sportsters.

FRISCO AND SPORTY MOUNT TANKS

Frisco mounting raises the tank onto the frame backbone, cleaning up the midsection on a chopper or hardtail Sportster build. The right width depends on how stretched or tight the build runs:

• Lowbrow Customs Frisco lineup: Standard, narrow, and super narrow widths from 1.6 to 2.5 gallons for 1986 to 2003 Sportsters. The King P-Nut Frisco pairs the raised backbone position with a peanut silhouette. Bayonet filler cap versions available on both standard and narrow profiles.

• Cycle Standard Frisco: Sportster-style narrow Frisco at 2.1 gallons and an EFI-specific Frisco mount for 2007 to 2022 fuel-injected Sportsters at 2.5 gallons.

PEANUT, BANANA AND CHOPPER TANKS

• Peanut tanks: Lowbrow Customs P-Nut in deep, mid, and shallow tunnel from 1.8 to 2.4 gallons. Cycle Standard Wassell peanut tanks in mid-tunnel, deep tunnel, dished Frisco mount, and narrow variants. Three tunnel depths let builders match the tank to the backbone height without shimming.

• Banana tanks: Lowbrow Customs Super Banana at 2.6 gallons and the Frisco mount banana with bayonet filler for builds where a peanut reads too short on the frame.

• Coffin and axed profiles: Lowbrow Customs Coffin at 1.4 gallons for the most minimal single-cap builds. Cycle Standard Axed Chopper in single and dual-cap versions at 2.2 gallons for an angular modern chopper direction.

BIG TWIN AND STOCK REPLACEMENT TANKS

• WX Split Tanks: Lowbrow Customs WX split tanks bolt onto 1936 to 1984 Big Twins at 2.25 gallons. Among the most reviewed tanks in the catalog and the correct visual choice for Panhead and Shovelhead choppers where a single-tank profile reads wrong.

• Fat Bob Tanks: Cycle Standard and Drag Specialties Fat Bob tanks for 1948 to 1984 FX/FL Big Twins and 1984 to 1999 Softails in 3.5 and 5-gallon versions for builds where range matters.

• Stock Replacements: Cycle Standard replica tanks for Ironhead Sportsters from 1958 to 1978 and Evo Sportsters from 1986 to 2003. The Blackbird Legacy covers 2007 to 2022 EFI Sportsters at 3.5 gallons for late-model builds needing more capacity.
