Positioned in Yamaha's scooter motorcycle lineup, the 2008 Yamaha TMax ABS features a 499 cc (30.5 cu in) liquid-cooled engine configuration. In factory specification, peak output is rated at 42.9 HP (31.3 kW) at 7,500 rpm while maximum torque reaches 36.3 Nm (26.8 lb-ft) at 3,700 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 86 HP per liter and a 3,800 rpm working window between peak torque (3,700 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 TMax ABS measures 203 kg (448 lbs) dry, translating to a power-to-weight ratio of 0.21 HP/kg (4.73 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 mm (0 in) wheelbase engineered for quick, flickable steering geometry. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
