The Perfect Balance of Range and Style: V-Twin Mfg. 3.1 Gallon King Tank

For decades, the Harley-Davidson Sportster has been defined by its lean, aggressive profile, centered around the legendary “peanut” fuel tank. However, for riders of the 1982–1992 era, the stock 2.2-gallon capacity can feel restrictive on long-distance hauls. The V-Twin Mfg. 3.1 Gallon King Tank is the definitive solution, offering an “oversized” version of the classic peanut shape. This “King” tank provides a more muscular, wide-shouldered appearance while boosting your fuel reserves, allowing you to stay in the saddle longer. Whether you are riding a late-model Ironhead or an early Evolution Sportster, this tank offers a seamless blend of heritage aesthetics and modern touring practicality.

Precision Fitment for the 1982–1992 XL Era

The decade spanning 1982 to 1992 was a transformative time for the Sportster, and finding parts that respect the specific frame dimensions of this era is crucial. This V-Twin Mfg. tank is a high-quality replacement for OEM part number 61091-83. It is designed to bolt directly to the factory mounting points found on 1982 through 1992 Sportster frames. Because it is built to original-style specifications, it maintains the correct clearance for your top motor mounts and rocker boxes, ensuring a clean and professional installation. This tank is the perfect choice for riders who want to upgrade their fuel volume while keeping the bike’s center of gravity low and its handling nimble.

Heavy-Duty Steel Construction and Technical Specs

Durability is a non-negotiable requirement for any fuel vessel. This King tank is constructed from high-tensile, heavy-gauge steel, precision-stamped to provide smooth, uniform curves. The one-piece design eliminates unnecessary seams, reducing the risk of stress fractures from engine vibration.

• Capacity: 3.1 Gallons (approx. 11.7 liters) for a significant range boost.
• Petcock Compatibility: Threaded for a standard 22mm external thread petcock on the left side.
• Gas Cap Style: Designed for 1983-up screw-in style vented gas caps, providing a modern and secure seal.
• Finish: Arrives in raw steel, prepared for bodywork and custom paint application.

Professional Preparation for Custom Painters

This tank arrives in a raw, unfinished steel state, offering a pristine canvas for your creative vision. Whether you are planning a period-correct “Sporty” stripe design or a high-end custom metal flake finish, the smooth surface of the King tank is ready for professional prep. To ensure the longevity of your build, we strongly recommend that the tank be pressure tested for leaks and treated with a high-quality internal tank sealer before painting. This protects the steel from the corrosive effects of modern ethanol fuels and prevents internal rust. Always perform a “dry fit” on your Sportster frame before painting to check for clearance against your handlebars, triple trees, and seat.
