Overview[edit | edit source]
AJS Model E1 / E2
The history of AJS dates back to 1897 when the Stevens brothers assembled the first Stevens motorcycle using an American made Mitchell engine. The first of the famous line of side-valve twins was the Model D of 1912, having a capacity of 698cc. Various engine capacities were used in the ensuing years, the 1925 model being of 799cc although the intention had been to introduce a 900cc version. Rather oddly, AJS who had been the innovators of the saddle tank, dropped this when introducing their new frame for the 1925 season and reverted to the older style of carrying the tank between the top tubes. Two versions of the Model E1 were available, the de-luxe having fully enclosed driving chains and Lucas magdyno lighting, whilst the austerity model had chain guards only and no lighting set.
