The Panther Model 100 is a British motorcycle. It has a 598 cc, 6.5:1 compression ratio, 87 mm × 100 mm (3.43 in × 3.94 in), OHV sloper engine in a frame where the engine forms the front down-tube. Phelon & Moore made motorcycles in Cleckheaton, Yorkshire, from 1904 to 1967, and branded them "Panther" from the 1920s onward. Launched in 1932, the Model 100 was made until 1963. While the engine and overall layout stayed essentially the same, the specifications evolved over these three decades.
