At the heart of the 2019 Derbi Senda X-Treme 50 SM super motard motorcycle, Derbi features a 50 cc (3.1 cu in) liquid-cooled single cylinder, two-stroke configuration. Internal engine geometry specifies a bore and stroke of 39.9 x 40.0 mm (1.6 x 1.6 inches) with a 11.5:1 compression ratio.
On the scales, the Senda X-Treme 50 SM measures 99 kg (218 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 880 mm (34.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,365 mm (53.7 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
