Engineered by Znen for the scooter motorcycle segment, the 2024 Znen R9 pairs a 49.6 cc (3 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 3.2 HP (2.4 kW) at 8,000 rpm while maximum torque reaches 2.8 Nm (2.1 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.5 mm (1.5 x 1.6 inches) with a 10.5:1 compression ratio.
On the scales, the R9 measures 83 kg (183 lbs) dry. Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 8.5-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 55 km/h (34 mph).
