At the heart of the 2020 Hm Derapage 125 super motard motorcycle, Hm pairs a 124.7 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 52.0 x 58.6 mm (2.0 x 2.3 inches) with a 12.0:1 compression ratio.
On the scales, the Derapage 125 measures 108.5 kg (239 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 1,395 mm (54.9 in) wheelbase engineered for quick, flickable steering geometry. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
