2006 Yamaha BWs Next Generation Technical Analysis & Specification Breakdown
Positioned in Yamaha's scooter motorcycle lineup, the 2006 Yamaha BWs Next Generation pairs a 49 cc (3 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 3.6 HP (2.6 kW) at 6,800 rpm while maximum torque reaches 4 Nm (3 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and 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 11.2:1 compression ratio.
On the scales, the BWs Next Generation measures 77 kg (170 lbs) dry. Rider ergonomics and chassis geometry center around a 803 mm (31.6 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,206 mm (47.5 in) wheelbase engineered for quick, flickable steering geometry. The 6.5-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
