Yamaha TRX 850

Yamaha TRX 850

The Yamaha TRX 850, produced in the late 1990s, holds a unique position in Yamaha’s lineup as a sport-touring motorcycle that aimed to blend performance with comfort. Powered by a liquid-cooled, 849cc parallel-twin engine, the TRX 850 offered a distinctive alternative to the more common inline-four configurations. The 5-valve per cylinder design contributed to the engine’s efficiency and responsiveness, delivering approximately 80 horsepower and 77 Nm of torque. This powerplant was mated to a 5-speed constant mesh transmission, providing riders with a versatile range for both spirited rides and highway cruising.

In terms of design, the Yamaha TRX 850 boasted a sport-touring aesthetic with a tubular steel backbone frame, dual headlights, and a dual exhaust system. The bike featured a comfortable riding position, making it suitable for long-distance journeys, and the monoshock rear suspension with linkage ensured a balanced and controlled ride. While the TRX 850 had a relatively short production run, its unique parallel-twin configuration and sport-touring characteristics have earned it a dedicated following among motorcycle enthusiasts who appreciate its blend of performance and touring capabilities.
