Positioned in Cagiva's custom - cruiser motorcycle lineup, the 1999 Cagiva Roadster 125 pairs a 124.6 cc (7.6 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 15 HP (10.9 kW) at 9,000 rpm while maximum torque reaches 18 Nm (13.3 lb-ft) at 9,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 120.4 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the Roadster 125 measures 134 kg (295 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (8.93 kg per horsepower). Rider ergonomics and chassis geometry center around a 740 mm (29.1 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 11-liter (2.9 US gal) fuel tank paired with a rated consumption of 6 L/100 km provides an estimated theoretical range of roughly 183 km (114 miles) between fill-ups, while factory top speed is listed at 104 km/h (65 mph).
