Built around Kayo's enduro - offroad motorcycle platform, the 2025 Kayo K4 relies on a 249.9 cc (15.3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 18.8 HP (13.7 kW) at 8,500 rpm while maximum torque reaches 18 Nm (13.3 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 75.2 HP per liter and a 2,000 rpm working window between peak torque (6,500 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 K4 measures 115.5 kg (255 lbs) dry, translating to a power-to-weight ratio of 0.16 HP/kg (6.14 kg per horsepower). Rider ergonomics and chassis geometry center around a 925 mm (36.4 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,455 mm (57.3 in) wheelbase engineered for balanced agility and highway composure. The 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
