At the heart of the 2012 Derbi Rambla 300i scooter motorcycle, Derbi utilizes a 278.3 cc (17 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 22.5 HP (16.4 kW) at 7,250 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 80.8 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Rambla 300i measures 146 kg (322 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.49 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.
