The 1974 AJS Y 4 250 Mk 2 represents a classic era of motorcycling. Its 247cc engine produces 25 horsepower at 7000 RPM, delivering a spirited riding experience. The seat height of 762mm (30.0 inches) is typical for bikes of this period, and its relatively light weight of 104.3kg (230.0 pounds) contributes to agile handling. The 7.57-liter (2.00 US gallons) fuel tank is adequate for shorter rides and weekend excursions. The Y 4 250 Mk 2 features a 4-speed gearbox, providing a direct connection to the engine's power. The front suspension utilizes telescopic forks, a common design for the time. Braking is handled by an expanding drum brake at the front, reflecting the technology available in the 1970s. This AJS model offers a taste of vintage motorcycling. Its classic styling, nimble handling, and responsive engine make it a desirable choice for enthusiasts seeking a retro riding experience. It's best suited for riders who appreciate the charm and character of motorcycles from a bygone era.
