Built around Derbi's super motard motorcycle platform, the 2011 Derbi Senda Baja 125 SM relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 56.5 x 49.5 mm (2.2 x 1.9 inches) with a 9.2:1 compression ratio.
On the scales, the Senda Baja 125 SM measures 128 kg (282 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 845 mm (33.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,452 mm (57.2 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.
