2010 Derbi Terra 125 Technical Analysis & Specification Breakdown

Positioned in Derbi's allround motorcycle lineup, the 2010 Derbi Terra 125 pairs a 124.2 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 15 HP (10.9 kW) at 9,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 120.8 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the Terra 125 measures 130 kg (287 lbs) wet (curb), translating to a power-to-weight ratio of 0.12 HP/kg (8.67 kg per horsepower). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
