With the G15 line, AMC built on the merits of the G12 but there were numerous changes to frame, forks, swinging arm, primary chaincase, transmission, cycle parts and lubrication system. The P11 was the last line of bikes with bonds to AMC. It used a modified G85CS frame but there were stronger forks, completely new cycle parts (making some was rather costly), altered lubrication and modified primary chaincases, to mention a few.
The G15 series was offered as 3 brands: Matchless G15 comprising G15Mk2, G15CS and G15CSR; AJS Model 33 comprising M33Mk2, M33CS and M33CSR; and last not least Norton N15CS (no Norton-branded roadster made as it would compete against the Atlas). The G15 series was produced from 1963 to 1969. They were initially for export only, but by 1965 these models were available in UK and Europe too.

Norton Villiers (1966–73)
In 1966 Associated Motorcycles went bankrupt and was taken over by Manganese Bronze Holdings, who formed Norton-Villiers to oversee operations. At the time Norton was the only motorcycle marque in the company that was making money. There was a P11 series which comprised the following four models; P11 (1967), P11A (1968) and P11A Ranger (1968/69) and the P11 Ranger 750 (1969). It is believed that production of the G15 series was halted late in 1968 (model year '69) with unsold samples on offer through 1969. The P11 series carried on in production until the spring of 1969. The P11 was offered either as Norton or Matchless, but by heritage it is a Matchless bike.
