Technical Overview
2014 Sonik Siena Technical Analysis & Specification Breakdown
At the heart of the 2014 Sonik Siena scooter motorcycle, Sonik utilizes a 49.5 cc (3 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 2.5 HP (1.8 kW) at 7,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.5 mm (1.5 x 1.6 inches) with a 10.5:1 compression ratio.
On the scales, the Siena measures 75 kg (165 lbs) dry. Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,250 mm (49.2 in) wheelbase engineered for quick, flickable steering geometry. The 4.5-liter (1.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 45 km/h (28 mph).
