2019 Kawasaki Z125 Pro Technical Analysis & Specification Breakdown
Positioned in Kawasaki's naked motorcycle lineup, the 2019 Kawasaki Z125 Pro relies on a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, maximum torque reaches 9.5 Nm (7 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 56.0 x 50.6 mm (2.2 x 2.0 inches) with a 9.8:1 compression ratio.
On the scales, the Z125 Pro measures 102 kg (225 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,176 mm (46.3 in) wheelbase engineered for quick, flickable steering geometry. The 7.57-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
