Built around Kymco's scooter motorcycle platform, the 2004 Kymco Spike 125 pairs a 120.4 cc (7.4 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 8.9 HP (6.5 kW) at 8,000 rpm while maximum torque reaches 9.5 Nm (7 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 4-speed gearbox. With a specific output of 73.9 HP per liter and a 1,500 rpm working window between peak torque (6,500 rpm) and peak power (8,000 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 Spike 125 measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (13.48 kg per horsepower).
