The 1973 Yamaha RD 250 (5-speed) emerged during a golden era for two-stroke motorcycles, solidifying Yamaha's reputation for producing accessible and spirited machines. This particular model continued the RD lineage, building on the success of earlier DT and DS series bikes, and directly challenged rivals like the Kawasaki S1 250 and Suzuki GT250 in the quarter-liter sportbike segment. It represented a significant step forward in performance and rideability for its class, becoming a popular choice for riders seeking a lightweight yet capable machine.

At the heart of the RD 250 was its 247.00 ccm (15.07 cubic inches) twin, two-stroke engine. This lively powerplant was rated at 30.00 HP (21.9 kW) delivered at a spirited 7500 RPM. Power was managed through a 5-speed transmission, allowing riders to effectively keep the engine in its powerband. This combination propelled the RD 250 to a top speed of 155.0 km/h (96.3 mph), a respectable figure for its time and displacement. Fuel capacity stood at 16.00 litres (4.23 gallons), offering a decent range for spirited rides or daily commutes.

Riding the RD 250 offered a distinct experience. Its lightweight chassis and relatively compact dimensions contributed to nimble handling, making it enjoyable on winding roads. The two-stroke engine delivered its power in a characteristic surge, demanding precise gear changes to maintain momentum. While not a touring machine, its ergonomics were generally comfortable for shorter to medium rides, offering a slightly forward-leaning stance that was common for sport-oriented bikes of the era. The bike's simplicity also meant straightforward maintenance, a significant appeal for many owners.

As a Vintage category motorcycle, the 1973 Yamaha RD 250 appeals to enthusiasts looking to experience the raw, engaging character of a classic two-stroke. It's a bike for those who appreciate mechanical simplicity, the distinctive sound and smell of a two-stroke engine, and the satisfaction of mastering its power delivery. Collectors and riders seeking an authentic piece of 1970s motorcycling history will find the RD 250 to be a rewarding and engaging machine, offering a tangible connection to a bygone era of motorcycling excitement.
