Technical Overview
2005 Jawa 125 Sport Technical Analysis & Specification Breakdown
Built around Jawa's enduro - offroad motorcycle platform, the 2005 Jawa 125 Sport features a 124 cc (7.6 cu in) 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. 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 Sport measures 99 kg (218 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.86 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 1,330 mm (52.4 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 108 km/h (67 mph).
