Turbocharged AJS racer

.





Here's the turbocharged AJS racer, an incredibly innovative 50-degree V4 from 1939. It had an overhead cam, was water-cooled, two were made, and there is only one remaining.
In 1935 at the London motorcycle show AJS unveiled the prototype of an air-cooled four cylinder touring bike. Over the next four years AJS refined the motorcycle for racing.via : www.bikermetric.com
