Positioned in Suzuki's custom - cruiser motorcycle lineup, the 2011 Suzuki GZ 125 utilizes a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 12 HP (8.8 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 96 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the GZ 125 measures 140 kg (309 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (11.67 kg per horsepower). Rider ergonomics and chassis geometry center around a 680 mm (26.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 15.9-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
