Built around Jawa-CZ's sport motorcycle platform, the 2009 Jawa-CZ 125 Dandy utilizes a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 12.6 HP (9.2 kW) while maximum torque reaches 9.2 Nm (6.8 lb-ft), 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, 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 Dandy measures 103 kg (227 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.17 kg per horsepower). Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 6.5-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 107 km/h (66 mph).
