Engineered by Hm for the super motard motorcycle segment, the 2020 Hm Derapage RR 125 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 RR 125 measures 104.5 kg (230 lbs) dry. Rider ergonomics and chassis geometry center around a 870 mm (34.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,410 mm (55.5 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.
