At the heart of the 1988 Suzuki RF 125 cross - motocross motorcycle, Suzuki relies on a 125 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 35 HP (25.5 kW) at 12,000 rpm while maximum torque reaches 30 Nm (22.1 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 280 HP per liter and a 4,000 rpm working window between peak torque (8,000 rpm) and peak power (12,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the RF 125 measures 100 kg (220 lbs) wet (curb), translating to a power-to-weight ratio of 0.35 HP/kg (2.86 kg per horsepower).

Power
Compare engine output with similar motorcycles if acceleration, highway use or two-up riding matters.
Torque
Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
