At the heart of the 2021 Sinnis 125 Terrain enduro - offroad motorcycle, Sinnis 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 11.1 HP (8.1 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 88.8 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 125 Terrain measures 150 kg (331 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (13.51 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 1,370 mm (53.9 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
