Built around Yamaha's scooter motorcycle platform, the 2011 Yamaha Vox Deluxe utilizes a 49 cc (3 cu in) air-cooled single cylinder, four-stroke layout. 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 95 kg (209 lbs) wet (curb). 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, combined with a 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry. The 4.5-liter (1.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
