Built around Keeway's allround motorcycle platform, the 2021 Keeway RKS 150 GS features a 148 cc (9 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 11 HP (8 kW) at 8,500 rpm while maximum torque reaches 10 Nm (7.4 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 74.3 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 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 RKS 150 GS measures 117 kg (258 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.64 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 95 km/h (59 mph).
