2025 Royal Alloy GP 125 LC Technical Analysis & Specification Breakdown
Built around Royal's scooter motorcycle platform, the 2025 Royal Alloy GP 125 LC utilizes a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 12.7 HP (9.3 kW) at 9,500 rpm while maximum torque reaches 10 Nm (7.4 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 101.6 HP per liter and a 2,000 rpm working window between peak torque (7,500 rpm) and peak power (9,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,390 mm (54.7 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 105 km/h (65 mph).
