Built around Jawa-CZ's sport motorcycle platform, the 2006 Jawa-CZ 650 Classic features a 651.9 cc (39.8 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, 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. Internal engine geometry specifies a bore and stroke of 100.0 x 83.0 mm (3.9 x 3.3 inches) with a 9.7:1 compression ratio.
On the scales, the 650 Classic measures 180 kg (397 lbs) dry. 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 13.5-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
