2023 Suzuki Best 125 Fi Technical Analysis & Specification Breakdown
Positioned in Suzuki's scooter motorcycle lineup, the 2023 Suzuki Best 125 Fi utilizes a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 9.4 HP (6.8 kW) at 8,000 rpm while maximum torque reaches 10.1 Nm (7.4 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 75.8 HP per liter and a 3,000 rpm working window between peak torque (5,000 rpm) and peak power (8,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Best 125 Fi measures 103 kg (227 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.96 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,240 mm (48.8 in) wheelbase engineered for quick, flickable steering geometry. The 4.3-liter (1.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
