Positioned in Jawa-CZ's sport motorcycle lineup, the 2010 Jawa-CZ 50 Robby relies on a 49.5 cc (3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 3 HP (2.2 kW) at 9,250 rpm while maximum torque reaches 3.2 Nm (2.4 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.4 mm (1.5 x 1.6 inches) with a 8.5:1 compression ratio.
On the scales, the 50 Robby measures 93 kg (205 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 730 mm (28.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,200 mm (47.2 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 48 km/h (30 mph).
Within MotoLibrary's Jawa-CZ archive, this model family spans 8 indexed model years from 2006 to 2014, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
