Engineered by Kawasaki for the naked motorcycle segment, the 2008 Kawasaki ER-6n features a 649 cc (39.6 cu in) liquid-cooled twin, four-stroke configuration. In factory specification, maximum torque reaches 48.5 Nm (35.8 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 83.0 x 60.0 mm (3.3 x 2.4 inches) with a 11.3:1 compression ratio.
On the scales, the ER-6n measures 174 kg (384 lbs) dry. Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 15.5-liter (4.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
