BSA motorcycles span a broad range of engine designs and riding conditions, and AMSOIL maintains the matched recommendation for every covered year and engine.
AMSOIL keeps the BSA recommendation in its live lookup, where the current product match can change as formulas and factory requirements change. Motorcycle oils in the lineup are built for wet-clutch compatibility and hard riding heat. Pick a model below, then confirm the live result before ordering.
Frequently asked questions
Which AMSOIL oil is recommended for a BSA motorcycle?
It depends on the model, year, and engine. AMSOIL maintains a live recommendation per configuration. Pick your BSA model in the grid above and click through to the AMSOIL lookup result for your exact engine.
Does AMSOIL meet BSA factory specifications?
Yes. AMSOIL formulates its current motorcycle oils to meet or exceed BSA factory specifications across the covered range where the formula qualifies. The lookup tool returns the product matched to the spec for your specific year and engine.
