The P11 series was a completely new development for 1967 and was further developed for 1968-69. The P11 was available either as Norton or Matchless.
The American importer Berliner Motor Corporation [1] sent AMC an example of a custom desert racer using a Norton 750 motor in a G80CS frame, and asked them to build them some. This was the last Matchless motorcycle, the 748cc G15 which was also sold as the AJS Model 33 and as the Norton P11.
Notes. 1. It is believed that Bob Blair, the West Coast distributor, built the desert racer which was sent to Britain.
