Their construction and fitment help reduce leaks, improve ride confidence, and elevate the look of your bike.

Choose the Right Tank for Your Ride

5 Gallon Fatbob Tank – Wide & Classic

The 5 Gallon Fatbob tank is built for riders who want maximum fuel range and a bold presence. Its larger volume means fewer stops on long rides, while the wide tank profile gives your bike a solid, balanced look. It comes with Cam-style caps and a 22mm petcock opening for traditional Big Twin fuel setups. Benefits:

Longer riding range between fill-ups
Bold stance and classic Fatbob silhouette
Easy cap access with common Cam-style openings
Ample room for custom paint or graphics

3.5 Gallon Hand Shift Tank – Compact & Classic

The 3.5 Gallon Hand Shift tank option suits riders who prefer a more classic riding feel or want a lighter front end. With its slightly smaller capacity, it works well on tighter frame builds and hand-shift style setups. This tank maintains a vintage look while still offering dependable fuel storage for everyday riding. Benefits:

Classic look for vintage or retro builds
Lighter weight for agile handling
Clean lines that match restored Big Twins
Fits hand shift configurations

Built for Big Twin Motorcycles

Both tank variations are engineered to match Big Twin frame geometry with trustworthy fitment. Their internal design supports smooth fuel flow and minimizes turbulence, giving you steady fuel delivery under normal street riding conditions. These tanks also offer plenty of space for custom paint or decals. Builders and riders alike value how easily both versions clean up into classic or modern custom paint schemes.
