Engineered by Kawasaki for the classic motorcycle segment, the 2024 Kawasaki Z650RS ABS utilizes a 649 cc (39.6 cu in) liquid-cooled twin, four-stroke layout. In factory specification, peak output is rated at 67.3 HP (49.1 kW) at 8,000 rpm while maximum torque reaches 65.7 Nm (48.5 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 103.7 HP per liter and a 1,500 rpm working window between peak torque (6,500 rpm) and peak power (8,000 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 Z650RS ABS measures 187 kg (412 lbs) wet (curb), translating to a power-to-weight ratio of 0.36 HP/kg (2.78 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 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 12.11-liter (3.2 US gal) fuel tank paired with a rated consumption of 4.44 L/100 km provides an estimated theoretical range of roughly 273 km (170 miles) between fill-ups.
