Engineered by Kawasaki for the naked motorcycle segment, the 2016 Kawasaki ER-6n utilizes a 649 cc (39.6 cu in) liquid-cooled twin, four-stroke layout. In factory specification, peak output is rated at 72 HP (52.6 kW) at 8,500 rpm while maximum torque reaches 64 Nm (47.2 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 110.9 HP per liter and a 2,000 rpm working window between peak torque (6,500 rpm) and peak power (8,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the ER-6n measures 204 kg (450 lbs) wet (curb), translating to a power-to-weight ratio of 0.35 HP/kg (2.83 kg per horsepower). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
