Built around Derbi's scooter motorcycle platform, the 2012 Derbi Rambla 125 features a 124 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 9,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 119.4 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 Rambla 125 measures 144 kg (317 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (9.73 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 1,360 mm (53.5 in) wheelbase engineered for quick, flickable steering geometry. The 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
