2006 Honda CBR 125 R Technical Analysis & Specification Breakdown
Built around Honda's sport motorcycle platform, the 2006 Honda CBR 125 R utilizes a 124.7 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 13 HP (9.5 kW) at 10,000 rpm while maximum torque reaches 10.1 Nm (7.4 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 104.3 HP per liter and a 2,000 rpm working window between peak torque (8,000 rpm) and peak power (10,000 rpm), 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 CBR 125 R measures 115 kg (254 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (8.85 kg per horsepower). Rider ergonomics and chassis geometry center around a 776 mm (30.6 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,294 mm (50.9 in) wheelbase engineered for quick, flickable steering geometry. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
