At the heart of the 2010 Yamaha Neos 4 Stroke scooter motorcycle, Yamaha utilizes a 49.4 cc (3 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 3.1 HP (2.2 kW) at 7,000 rpm while maximum torque reaches 3.2 Nm (2.3 lb-ft) at 7,000 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 43.6 mm (1.5 x 1.7 inches) with a 12.0:1 compression ratio.
On the scales, the Neos 4 Stroke measures 95 kg (209 lbs) wet (curb). 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 5.4-liter (1.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
