Positioned in Malaguti's sport motorcycle lineup, the 2021 Malaguti RST125 pairs a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 10,750 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 118.4 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 RST125 measures 148 kg (326 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance.
