2017 Yamaha SZ-RR Version 2 Technical Analysis & Specification Breakdown
Built around Yamaha's allround motorcycle platform, the 2017 Yamaha SZ-RR Version 2 features a 149 cc (9.1 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12.1 HP (8.8 kW) at 11,000 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 81.2 HP per liter and a 5,000 rpm working window between peak torque (6,000 rpm) and peak power (11,000 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 SZ-RR Version 2 measures 134 kg (295 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.07 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.
