Norton P10

The Norton P10 was a prototype motorcycle designed by AMC in the 1960s. It used a unit construction 800 cc DOHC parallel twin engine. The model suffered from oil leaks and severe vibration during testing and was never put into production. Following the collapse of AMC in 1966 and the subsequent takeover by Manganese Bronze Holdings to form Norton-Villiers, the prototype was used as a starting point of the Z26, which was intended as a replacement for the Norton Atlas.
