Engineered by Hyosung for the trial motorcycle segment, the 2008 Hyosung RX125D-E pairs a 124 cc (7.6 cu in) oil & air-cooled single cylinder, four-stroke architecture with road-focused gearing.
On the scales, the RX125D-E measures 120 kg (265 lbs) dry. Rider ergonomics and chassis geometry center around a 850 mm (33.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,425 mm (56.1 in) wheelbase engineered for balanced agility and highway composure. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
Within MotoLibrary's Hyosung archive, this model family spans 2 indexed model years from 2008 to 2011, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
