Technical Overview
2007 Derbi 125 SM Baja Technical Analysis & Specification Breakdown
Engineered by Derbi for the super motard motorcycle segment, the 2007 Derbi 125 SM Baja pairs a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. 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 125 SM Baja measures 118 kg (260 lbs) dry. 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 9.5-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
