Engineered by Motorhispania for the sport motorcycle segment, the 2012 Motorhispania RX 125R relies on a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 15 HP (10.9 kW) at 9,000 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 120 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 RX 125R measures 135 kg (298 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (9 kg per horsepower). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,330 mm (52.4 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.
