At the heart of the 2017 Sinnis Shuttle 125 scooter motorcycle, Sinnis utilizes a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 7.6 HP (5.6 kW) at 7,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 61.3 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 Shuttle 125 measures 115 kg (254 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (15.13 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. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
