Oil Tanks

Custom Motorcycle Oil Tanks for Harley

A motorcycle oil tank does one job on a dry-sump Harley or Triumph: hold and circulate the oil that the frame no longer stores internally. Construction quality matters here more than on most parts, since a tank running dry or leaking oil at speed is a real mechanical risk, not just a cosmetic issue.

Capacity and Fitment by Model

Harley-Davidson Big Twins (Panhead, Shovelhead, Softail, and similar models) and XL Sportsters typically run oil tanks holding 3 to 4 quarts. This collection covers weld-on, bolt-on, and clamp-on mounting styles across a wide range of years, from 1936 Big Twins through 2022 Sportster hardtails, along with dedicated hardware for K, KH, and XLCH models.

Materials and Styles

Steel oil tanks in dimpled, domed, and smoothie styles cover most Harley chopper builds, while aluminum options, including finned Choppahead tanks and classic hot-rod-style Mooneyes tanks, suit a more polished custom look. Triumph and BSA riders have dedicated dimpled and domed steel tanks built with the correct fittings for the OEM-style Triumph oil feed filter and return T fitting.

Mounting Hardware and Fittings

Beyond the tanks themselves, this collection covers oil tank mounting hardware, brackets, oil line fittings, filler caps, drain plugs, and dipsticks for specific year ranges. Fitment is closely tied to frame type and mounting style, so check the product listing to confirm the tank and hardware match your bike's exact year and model before ordering.
