Technical Overview
2022 Royal Alloy TG 125 S Technical Analysis & Specification Breakdown
Built around Royal's scooter motorcycle platform, the 2022 Royal Alloy TG 125 S 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 9.5 HP (6.9 kW), transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 76 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 Alloy TG 125 S measures 148 kg (326 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (15.58 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 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
