2013 Jawa-CZ 125 Technical Analysis & Specification Breakdown

Built around Jawa-CZ's sport motorcycle platform, the 2013 Jawa-CZ 125 features a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12.6 HP (9.2 kW) at 8,200 rpm while maximum torque reaches 9.2 Nm (6.8 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 101.6 HP per liter and a 1,200 rpm working window between peak torque (7,000 rpm) and peak power (8,200 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the 125 measures 131 kg (289 lbs) wet (curb), translating to a power-to-weight ratio of 0.1 HP/kg (10.4 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,370 mm (53.9 in) wheelbase engineered for quick, flickable steering geometry. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 95 km/h (59 mph).
