Saddle Tank
« Back to Glossary Index
The term saddle tank refers to a type of fuel tank design used in various vehicles, particularly in trucks, motorcycles, and some heavy equipment. It can refer to different mounting configurations depending on the application:
1. Automotive/Truck Application
A saddle tank in trucks or large vehicles is a fuel tank mounted above or alongside the rear axle, typically straddling it like a saddle. These tanks are:
- Positioned on either side of the vehicle frame, often in pairs.
- Designed to maximize fuel capacity while maintaining vehicle balance.
- Common in commercial trucks, buses, and military vehicles.
Key Features:
- Accessible for refueling.
- Often constructed from steel or aluminum.
- May include fuel transfer systems for balancing fuel between tanks.
2. Motorcycle Application
In motorcycles, a saddle tank refers to a fuel tank that is mounted over the top frame tube, resembling the shape of a horse saddle draped across the bike’s spine.
Key Features:
- Classic design found in vintage and cruiser motorcycles.
- Positioned to lower the center of gravity and improve handling.
- May be split into two halves on either side of the frame for stylistic or functional reasons.
Summary:
A saddle tank earns its name from the way it “sits” over or around a part of the vehicle—like a saddle on a horse—either over the rear axle in trucks or the top frame tube in motorcycles. It is used primarily for fuel storage and weight distribution.
