Motorcycle museum record
The Commando isolated its engine and gearbox from the frame using the Isolastic mounting system, reducing the vibration that limited increasingly large British twins.

Technical identity
This first expansion records museum-level specifications rather than pretending every year and market used one immutable specification.
Research starting point
Model-year specifications can vary. The museum keeps the stable historical interpretation here and leaves room to add exact variants, racing derivatives, engine codes and source-specific specifications later.
