2012 Yamaha Jog Technical Analysis & Specification Breakdown
Built around Yamaha's scooter motorcycle platform, the 2012 Yamaha Jog relies on a 49 cc (3 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 40.0 x 39.2 mm (1.6 x 1.5 inches) with a 7.3:1 compression ratio.
On the scales, the Jog measures 74 kg (163 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 710 mm (28 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 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
