1994 Yamaha TDM 850 Technical Analysis & Specification Breakdown

Engineered by Yamaha for the motorcycle segment, the 1994 Yamaha TDM 850 relies on a 849 cc (51.8 cu in) twin, four-stroke powerplant. In factory specification, peak output is rated at 77 HP (56.2 kW) at 7,500 rpm while maximum torque reaches 79.4 Nm (58.6 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 90.7 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 TDM 850 measures 199 kg (439 lbs) dry, translating to a power-to-weight ratio of 0.39 HP/kg (2.58 kg per horsepower). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 18-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
