At the heart of the 2006 Jawa-CZ 50 Minarelli sport motorcycle, Jawa-CZ utilizes a 49.7 cc (3 cu in) liquid-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 6 HP (4.4 kW) at 8,700 rpm while maximum torque reaches 4.7 Nm (3.5 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 40.3 x 39.0 mm (1.6 x 1.5 inches) with a 12.0:1 compression ratio.
On the scales, the 50 Minarelli measures 88 kg (194 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (14.67 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,320 mm (52 in) wheelbase engineered for quick, flickable steering geometry. The 24.6-liter (6.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 90 km/h (56 mph).
