At the heart of the 2020 Sinnis Harrier scooter motorcycle, Sinnis features a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 8.2 HP (6 kW), transferring power to the rear wheel through belt final drive. With a specific output of 65.6 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 Harrier measures 100 kg (220 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.2 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,365 mm (53.7 in) wheelbase engineered for quick, flickable steering geometry.
