  • Made 1948-62. 348cc single-cylinder engine.

The Model 75 Panther motorcycle had a 348cc, 6.5:1 (later 6.7:1) compression ratio, 71 x 88 mm, ohv vertical engine in a relatively standard frame. It was developed from the 1948 Model 70. In many respects it was similar to the 248cc Model 65.

The Model 75 had Lucas K1F magneto ignition. The gearbox was Burman CP four speed unit with a ratio of 5.25:1. The frame was a heavy duty cradle with a single saddle down tube. A swinging arm model was introduced in 1953. The Dowty forks that initially provided front suspension were later replaced with the P&M telescopic forks. Wheels were 26" x 3.25" front and rear initially with 6" half width hubs and later optional alloy hubs were offered.

This model was largely a development of the Model 70.
