2022 Yamaha SZ Technical Analysis & Specification Breakdown

Engineered by Yamaha for the allround motorcycle segment, the 2022 Yamaha SZ features a 149.3 cc (9.1 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12.1 HP (8.8 kW) at 7,500 rpm while maximum torque reaches 12.8 Nm (9.4 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 81 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 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 SZ measures 133 kg (293 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (10.99 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,320 mm (52 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
