Positioned in Jawa-CZ's sport motorcycle lineup, the 2006 Jawa-CZ 100 Robby features a 97 cc (5.9 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 6.4 HP (4.6 kW) at 7,750 rpm while maximum torque reaches 6.5 Nm (4.8 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 66 HP per liter and a 2,250 rpm working window between peak torque (5,500 rpm) and peak power (7,750 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 100 Robby measures 82 kg (181 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.81 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 1,200 mm (47.2 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 80 km/h (50 mph).
