2015 Yamaha Jog Technical Analysis & Specification Breakdown
Engineered by Yamaha for the scooter motorcycle segment, the 2015 Yamaha Jog features a 49 cc (3 cu in) air-cooled single cylinder, two-stroke configuration. In factory specification, peak output is rated at 4.5 HP (3.3 kW) at 7,000 rpm while maximum torque reaches 4.2 Nm (3.1 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 43.5 mm (1.5 x 1.7 inches) with a 12.0:1 compression ratio.
On the scales, the Jog measures 84 kg (185 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 725 mm (28.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,160 mm (45.7 in) wheelbase engineered for quick, flickable steering geometry. The 5.5-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
