Positioned in WK's allround motorcycle lineup, the 2017 WK RT 125 Cafe features a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 10.5 HP (7.6 kW) at 8,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 84.7 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 RT 125 Cafe measures 106 kg (234 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.1 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 1,335 mm (52.6 in) wheelbase engineered for quick, flickable steering geometry. The 12.8-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
