Engineered by WK for the touring motorcycle segment, the 2017 WK 650TR features a 649 cc (39.6 cu in) air-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 69.7 HP (50.9 kW) at 8,500 rpm while maximum torque reaches 62 Nm (45.7 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 107.4 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 reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the 650TR measures 220 kg (485 lbs) dry, translating to a power-to-weight ratio of 0.32 HP/kg (3.16 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 1,414 mm (55.7 in) wheelbase engineered for quick, flickable steering geometry. The 17.5-liter (4.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
