2020 Royal Alloy GP 125 LC Technical Analysis & Specification Breakdown
Positioned in Royal's scooter motorcycle lineup, the 2020 Royal Alloy GP 125 LC utilizes a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, maximum torque reaches 10.5 Nm (7.7 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a 12.0:1 compression ratio.
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).
