Technical Overview
2017 Jawa-CZ 350 Military Technical Analysis & Specification Breakdown
Engineered by Jawa-CZ for the sport motorcycle segment, the 2017 Jawa-CZ 350 Military features a 343.5 cc (21 cu in) air-cooled twin, two-stroke configuration. In factory specification, peak output is rated at 22.8 HP (16.6 kW) at 5,250 rpm while maximum torque reaches 32 Nm (23.6 lb-ft) at 4,750 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 66.4 HP per liter and a 500 rpm working window between peak torque (4,750 rpm) and peak power (5,250 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the 350 Military measures 154 kg (340 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.75 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 1,350 mm (53.1 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 120 km/h (75 mph).
