Built around Vent's super motard motorcycle platform, the 2020 Vent Derapage 50 utilizes a 49.7 cc (3 cu in) liquid-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 40.3 x 39.0 mm (1.6 x 1.5 inches).
On the scales, the Derapage 50 measures 87 kg (192 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.
Within MotoLibrary's Vent archive, this model family spans 2 indexed model years from 2020 to 2023, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
