Engineered by Keeway for the sport motorcycle segment, the 2007 Keeway RX3 utilizes a 49.8 cc (3 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 12.8 HP (9.3 kW) at 13,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 1.5 x 0.0 mm (0.1 x inches).
On the scales, the RX3 measures 175 kg (386 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (13.67 kg per horsepower). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,400 mm (55.1 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 135 km/h (84 mph).
