Built around Yamaha's allround motorcycle platform, the 2018 Yamaha SZR relies on a 123 cc (7.5 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, maximum torque reaches 10.4 Nm (7.7 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 54.0 x 54.0 mm (2.1 x 2.1 inches) with a 10.0:1 compression ratio.
On the scales, the SZR measures 125 kg (276 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,295 mm (51 in) wheelbase engineered for quick, flickable steering geometry. The 13.6-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
