2012 Suzuki Skywave 400 Type S ABS Technical Analysis & Specification Breakdown

At the heart of the 2012 Suzuki Skywave 400 Type S ABS scooter motorcycle, Suzuki utilizes a 399 cc (24.4 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 30.8 HP (22.5 kW) at 7,000 rpm while maximum torque reaches 33 Nm (24.3 lb-ft) at 3,400 rpm, transferring power to the rear wheel through belt final drive. With a specific output of 77.2 HP per liter and a 3,600 rpm working window between peak torque (3,400 rpm) and peak power (7,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the Skywave 400 Type S ABS measures 223 kg (492 lbs) dry, translating to a power-to-weight ratio of 0.14 HP/kg (7.24 kg per horsepower). Rider ergonomics and chassis geometry center around a 710 mm (28 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
