1979
The 1979 Yamaha DT 250 F represents a significant chapter in the evolution of dual-sport motorcycles. As part of Yamaha's highly successful DT series, the '79 F model continued the tradition of offering a versatile machine capable of handling varied terrains. This particular iteration built upon the foundation of its predecessors, aiming to strike a balance between off-road capability and on-road usability. In its competitive landscape, the DT 250 F was often pitted against rivals like the Honda XL250 and Suzuki PE250, all vying for dominance in the burgeoning quarter-liter dual-sport segment.
At the heart of the DT 250 F lies a robust 246.0 ccm (15.01 cubic inches) two-stroke engine. This single-cylinder powerplant was renowned for its punchy delivery, a characteristic that made it a favorite for both trail riding and daily commutes. The motorcycle's top speed was rated at 109.0 km/h (67.7 mph), a respectable figure for a dual-sport of its era, allowing it to keep pace with traffic on most roads. Fuel capacity stood at 9.00 litres (2.38 US gallons), providing a decent range for extended rides without frequent stops at the pump.
Riding characteristics of the DT 250 F were defined by its purpose-built design. The upright stance and wide handlebars offered excellent leverage and control, particularly when navigating technical off-road sections. Its relatively long-travel suspension, a hallmark of dual-sport machines, effectively absorbed bumps and uneven surfaces, contributing to a comfortable ride over varied terrain. While not designed for aggressive road carving, its moderate weight and responsive engine made it an agile machine for its class, capable of agile maneuvers on loose surfaces and through winding trails.
The Yamaha DT 250 F was primarily aimed at riders seeking a practical and enjoyable motorcycle for both recreational off-road excursions and utility-focused daily use. It appealed to a broad demographic, from novice riders looking for an accessible entry into motorcycling to experienced enthusiasts desiring a reliable and low-maintenance trail bike. Its blend of simplicity, durability, and a capable two-stroke engine cemented its place as a go-to choice for those who valued versatility and ruggedness in their two-wheeled companion.
