Built around Orcal's naked motorcycle platform, the 2023 Orcal SK01 125 utilizes a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 13.4 HP (9.8 kW) at 9,500 rpm while maximum torque reaches 12.8 Nm (9.4 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 107.2 HP per liter and a 1,500 rpm working window between peak torque (8,000 rpm) and peak power (9,500 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 SK01 125 measures 159 kg (351 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (11.87 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry. The 15.5-liter (4.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
