Collection: Oil tanks for Harley-Davidson, Indian and metric custom motorcycles

There's a tank that is rarely looked at – until it cracks, gets contaminated, or simply doesn't fit into a custom project. The oil tank is a critical component for engines where engine oil is stored in a separate unit from the engine block (typically classic Harley-Davidson and many custom V-Twin designs). It provides the volume and space from which the oil pump continuously supplies the engine with the necessary lubrication. In addition, classic, rounded or angular oil tanks are often characterful, highly visible elements of a motorcycle's appearance – especially on hardtail and bobber builds where there's nowhere to hide them. Our range includes oil tanks for Harley-Davidson, Indian, and metric custom motorcycles, from factory specification versions to clean, minimalist custom shapes. Available are tanks of various capacities and shapes – classic "batwing", horizontal and vertical designs – that fit both traditional and custom frames. Quality oil tanks are made from durable, corrosion-resistant materials, with a leak-proof design to reliably store and dispense engine oil for the long term. Whether you're replacing a damaged or leaking tank, or building a full custom bike, you'll find the oil tank that perfectly matches your motorcycle's style and needs here.
