TRX 850

1997 Yamaha TRX 850 Technical Analysis & Specification Breakdown

At the heart of the 1997 Yamaha TRX 850 allround motorcycle, Yamaha utilizes a 849 cc (51.8 cu in) air-cooled twin, four-stroke layout. In factory specification, peak output is rated at 83 HP (60.6 kW) at 7,500 rpm while maximum torque reaches 87 Nm (64.2 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 97.8 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 reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the TRX 850 measures 188 kg (414 lbs) dry, translating to a power-to-weight ratio of 0.44 HP/kg (2.27 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.
