1983 Honda CR 125 R Technical Analysis & Specification Breakdown
Engineered by Honda for the cross - motocross motorcycle segment, the 1983 Honda CR 125 R features a 124 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke configuration. In factory specification, peak output is rated at 31 HP (22.6 kW) at 11,000 rpm while maximum torque reaches 20 Nm (14.8 lb-ft) at 10,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 250 HP per liter and a 500 rpm working window between peak torque (10,500 rpm) and peak power (11,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the CR 125 R measures 86 kg (190 lbs) dry, translating to a power-to-weight ratio of 0.36 HP/kg (2.77 kg per horsepower). Rider ergonomics and chassis geometry center around a 930 mm (36.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,435 mm (56.5 in) wheelbase engineered for balanced agility and highway composure. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
