Overview

1924 Harley-Davidson Model JD: A Classic Allrounder Step back in time to 1924, a pivotal year for motorcycling enthusiasts, as Harley-Davidson unveiled the Model JD, a motorcycle that would capture the hearts of riders and collectors alike. Positioned as a versatile allrounder, the JD was designed to cater to a wide spectrum of riders, from urban commuters to long-distance travelers. This vintage motorcycle encapsulated the spirit of freedom and adventure, making it a beloved choice during the roaring twenties, an era marked by innovation and the thrill of the open road. At the heart of the Model JD lies a robust 1208 cc V2, four-stroke engine, delivering a modest yet spirited 12 horsepower. This power plant, coupled with its chain final drive, allows the JD to reach a top speed of 136.8 km/h (85.0 mph), showcasing its respectable performance for the time. Riders will appreciate its smooth operation, thanks to the carburettor fuel system and H.D. generator ignition, ensuring reliable starts and consistent throttle response. With a bore and stroke of 87.0 x 101.6 mm (3.4 x 4.0 inches), the engine produces a delightful rumble that resonates with the soul of classic motorcycling. Handling the Model JD is a rewarding experience, as its weight of 166 kg (366 pounds) strikes a balance between stability and agility, making both city cruising and country roads enjoyable. The Model JD is not just about power; it boasts several key features that highlight Harley-Davidson's commitment to innovation. The expanding rear drum brake enhances stopping power, providing riders with confidence as they navigate various terrains. Its timeless design showcases classic styling cues, with a streamlined silhouette and elegant lines that speak to the craftsmanship of the era. The Model JD also embodies the essence of early American motorcycling, with a design philosophy that prioritizes both functionality and aesthetics. **
