Positioned in Sinnis's super motard motorcycle lineup, the 2021 Sinnis Akuma 125 pairs a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 11 HP (8 kW) at 9,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 88 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Akuma 125 measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.91 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
