The Jog is a scooter produced by the Yamaha Motor Company since 1983, and was introduced in North America in 1986.

It continued production in North America after 3 style changes and model designations (CE50, CG50 and CY50) until 2001.

It was powered by an air-cooled two-stroke reed valve 49 cc (3.0 cu in) vertical Minarelli single-cylinder engine producing with 4.5 hp (3.4 kW) and 4.3 lb⋅ft (5.8 N⋅m) of torque.

The final North American revision the CY50 was released in 1992 and had the longest production run of any of the Jogs, ending in 2001.

It was a heavily restyled version of the CG50, but the engine was also changed from the air-cooled vertical Minarelli to the air-cooled 49 cc (3.0 cu in) horizontal Minarelli and the top speed was increased to 40 mph (64 km/h) in stock form.
