Simplex Automatic 1950 - Specifications & Review

Introducing the 1950 Simplex Automatic motorcycle, a quintessential piece of American engineering that embodies the spirit of post-war innovation and practicality. Positioned as an all-around commuter bike, the Simplex Automatic was designed for riders seeking a reliable and efficient mode of transportation without the complexities often associated with larger motorcycles. With its unique charm and user-friendly features, this lightweight machine quickly captured the hearts of motorcycle enthusiasts and everyday riders alike, making it a noteworthy contender in the burgeoning motorcycle market of the 1950s.

At the heart of the Simplex Automatic lies a single-cylinder, two-stroke engine displacing 130cc, which delivers a modest 4 horsepower at 4,000 RPM. This powerplant, while not designed for speed demons, offers a delightful balance of torque and efficiency, making city commuting smooth and enjoyable. The 6.5:1 compression ratio and the well-engineered carburettor fuel system contribute to its reliability, ensuring that the rider can trust the machine to start up and carry them through their daily journeys. The weight of just 61.2 kg (135 pounds) means that handling is light and nimble, allowing for easy maneuvering through crowded streets or narrow country lanes.

The design of the Simplex Automatic showcases thoughtful engineering and practical features. Its duplex loop frame provides strength while maintaining a lightweight profile, essential for a commuter bike. The front suspension, featuring short rocker arms combined with two coil springs, absorbs bumps effectively, allowing for a comfortable ride. In contrast, the rear suspension is rigid, promoting a direct connection to the road that many enthusiasts appreciate. With a fuel capacity of 9.46 liters (2.5 gallons), the Simplex is economical, delivering impressive mileage that keeps riders on the road longer and stops at the gas station fewer and farther between.
