AJS 1928 Model K 5 349 cc frame # K 124388 engine 124388
The four Stevens brothers had been in motorcycle manufacturing since the final years of the 19th century, but only in 1911 their first complete “AJS” motorcycle, a 298 cc two speeder, was marketed. For the 1912 season their first V- twin, the model D, was brought out. In the 1914 Junior TT a magnificent first and second place was scored.
The 350 cc AJS OHV machines from the twenties got their nickname “bigport” from the enormous size of the exhaust port and pipe.
Between 1920 and 1922 AJS was very successful in racing with 350cc ohv machines.
This also led to a great popularity for their more mundane side valve types.
From 1925 on prefixes were used to the numbering system: E=1925, G=1926, H=1927 K= 1928.
This machine is an older restoration.
