Built around Senke's custom - cruiser motorcycle platform, the 2021 Senke SK150 features a 149.4 cc (9.1 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 10.6 HP (7.7 kW) at 8,000 rpm while maximum torque reaches 10 Nm (7.4 lb-ft) at 6,500 rpm. With a specific output of 71 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 SK150 measures 98 kg (216 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.25 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry.
