At the heart of the 2016 Hyosung GT125R sport motorcycle, Hyosung utilizes a 124.5 cc (7.6 cu in) oil & air-cooled v2, four-stroke layout. Internal engine geometry specifies a 10.2:1 compression ratio.
On the scales, the GT125R measures 120 kg (265 lbs) dry. Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,435 mm (56.5 in) wheelbase engineered for balanced agility and highway composure. The 17-liter (4.5 US gal) fuel tank paired with a rated consumption of 3.02 L/100 km provides an estimated theoretical range of roughly 563 km (350 miles) between fill-ups.
Within MotoLibrary's Hyosung archive, this model family spans 6 indexed model years from 2008 to 2016, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
