Positioned in Yamaha's scooter motorcycle lineup, the 2008 Yamaha Neos 50 relies on a 49.2 cc (3 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 2.8 HP (2 kW) at 6,750 rpm while maximum torque reaches 3 Nm (2.2 lb-ft) at 6,500 rpm, transferring power to the rear wheel through chain final drive. Internal engine geometry specifies a bore and stroke of 40.0 x 39.2 mm (1.6 x 1.5 inches) with a 10.7:1 compression ratio.
On the scales, the Neos 50 measures 82 kg (181 lbs) dry. Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,275 mm (50.2 in) wheelbase engineered for quick, flickable steering geometry. The 6.1-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
