Technical Overview
2025 Royal Alloy GT 125 AC Technical Analysis & Specification Breakdown
Positioned in Royal's scooter motorcycle lineup, the 2025 Royal Alloy GT 125 AC utilizes a 124.6 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 9.5 HP (6.9 kW) at 7,500 rpm while maximum torque reaches 9.2 Nm (6.8 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 76.2 HP per liter and a 500 rpm working window between peak torque (7,000 rpm) and peak power (7,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Alloy GT 125 AC measures 130 kg (287 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (13.68 kg per horsepower). 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.
