AJS S9 from 1931
The “S9” was available in two versions, “ Light” and “ Heavy”.
There are few differences between the “L” and the “H”: different rear chain size, gear ratios, wheel base and petrol and oil tank capacity. However, the engine is the same in both versions.
This bike has old restoration with good general condition. It works properly.+
