Positioned in Jawa-CZ's classic motorcycle lineup, the 2008 Jawa-CZ 650 Classic pairs a 651.9 cc (39.8 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 47.5 HP (34.6 kW) at 6,500 rpm while maximum torque reaches 57 Nm (42 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 72.9 HP per liter and a 1,500 rpm working window between peak torque (5,000 rpm) and peak power (6,500 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 650 Classic measures 180 kg (397 lbs) dry, translating to a power-to-weight ratio of 0.26 HP/kg (3.79 kg per horsepower). Rider ergonomics and chassis geometry center around a 712 mm (28 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,525 mm (60 in) wheelbase engineered for planted straight-line stability. The 14.2-liter (3.8 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 155 km/h (96 mph).
