At the heart of the 2015 Yamaha Vox Deluxe scooter motorcycle, Yamaha relies on a 49 cc (3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 4.2 HP (3 kW) at 8,000 rpm while maximum torque reaches 3.9 Nm (2.9 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 38.0 x 43.5 mm (1.5 x 1.7 inches) with a 12.0:1 compression ratio.
On the scales, the Vox Deluxe measures 89 kg (196 lbs) dry. Rider ergonomics and chassis geometry center around a 735 mm (28.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 4.5-liter (1.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
