At the heart of the 2011 Derbi Senda Baja 125R enduro - offroad motorcycle, Derbi features a 124.1 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. 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 125R measures 118 kg (260 lbs) dry. Rider ergonomics and chassis geometry center around a 890 mm (35 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, 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.
