At the heart of the 2004 Kawasaki ER-5 touring motorcycle, Kawasaki relies on a 498 cc (30.4 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 49 HP (35.8 kW) at 9,000 rpm while maximum torque reaches 43 Nm (31.7 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 98.4 HP per liter, 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-5 measures 179 kg (395 lbs) dry, translating to a power-to-weight ratio of 0.27 HP/kg (3.65 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,430 mm (56.3 in) wheelbase engineered for balanced agility and highway composure. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 178 km/h (111 mph).
