Technical Overview
2016 Yamaha X-Max 250 Iron Max Technical Analysis & Specification Breakdown
Positioned in Yamaha's scooter motorcycle lineup, the 2016 Yamaha X-Max 250 Iron Max pairs a 249.8 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 20.1 HP (14.7 kW) at 7,500 rpm while maximum torque reaches 21 Nm (15.5 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 80.5 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 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 X-Max 250 Iron Max measures 182 kg (401 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (9.05 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 1,545 mm (60.8 in) wheelbase engineered for planted straight-line stability. The 13.2-liter (3.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
