Built around Yamaha's allround motorcycle platform, the 2010 Yamaha TDM 900A features a 897 cc (54.7 cu in) liquid-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 85 HP (62.1 kW) while maximum torque reaches 88.8 Nm (65.5 lb-ft) at 9,100 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 94.8 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the TDM 900A measures 223 kg (492 lbs) wet (curb), translating to a power-to-weight ratio of 0.38 HP/kg (2.62 kg per horsepower). Rider ergonomics and chassis geometry center around a 825 mm (32.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,485 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 20-liter (5.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
