Engineered by Yamaha for the scooter motorcycle segment, the 2020 Yamaha XMax 400 features a 395 cc (24.1 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 32.9 HP (24 kW) at 7,000 rpm while maximum torque reaches 36 Nm (26.6 lb-ft) at 6,000 rpm, transferring power to the rear wheel through belt final drive. With a specific output of 83.3 HP per liter and a 1,000 rpm working window between peak torque (6,000 rpm) and peak power (7,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the XMax 400 measures 210 kg (463 lbs) wet (curb), translating to a power-to-weight ratio of 0.16 HP/kg (6.38 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 1,567 mm (61.7 in) wheelbase engineered for planted straight-line stability. The 13-liter (3.4 US gal) fuel tank paired with a rated consumption of 4.1 L/100 km provides an estimated theoretical range of roughly 317 km (197 miles) between fill-ups.
