Planet 125

2003 Cagiva Planet 125 Technical Analysis & Specification Breakdown

Positioned in Cagiva's naked motorcycle lineup, the 2003 Cagiva Planet 125 utilizes a 124.6 cc (7.6 cu in) single cylinder, two-stroke layout. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 8,500 rpm while maximum torque reaches 12 Nm (8.9 lb-ft) at 7,000 rpm. With a specific output of 118.8 HP per liter and a 1,500 rpm working window between peak torque (7,000 rpm) and peak power (8,500 rpm), 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 Planet 125 measures 135 kg (298 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (9.12 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,385 mm (54.5 in) wheelbase engineered for quick, flickable steering geometry. The 12.5-liter (3.3 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 120 km/h (75 mph).
