ER-6n

2006 Kawasaki ER-6n Technical Analysis & Specification Breakdown

Built around Kawasaki's naked motorcycle platform, the 2006 Kawasaki ER-6n relies on a 649 cc (39.6 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 71.1 HP (51.9 kW) at 8,500 rpm while maximum torque reaches 66 Nm (48.7 lb-ft) at 6,700 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 109.6 HP per liter and a 1,800 rpm working window between peak torque (6,700 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 173 kg (381 lbs) dry, translating to a power-to-weight ratio of 0.41 HP/kg (2.43 kg per horsepower). 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, combined with a 1,405 mm (55.3 in) wheelbase engineered for quick, flickable steering geometry. The 15.5-liter (4.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
