Overview

Introducing the 1955 DKW RT 350 S, a hallmark of post-war motorcycle engineering that beautifully captures the spirit of the era. This all-rounder motorcycle was designed to cater to a wide range of riders, from daily commuters to weekend adventurers. With its robust build and innovative two-stroke twin engine, the RT 350 S quickly became a staple in the DKW lineup, providing a harmonious blend of practicality and performance. Its compact dimensions and manageable weight make it an accessible choice for both seasoned riders and newcomers looking to embrace the thrill of motorcycling. At the heart of the RT 350 S lies its spirited 348cc twin-cylinder, two-stroke engine, delivering a respectable 18.5 horsepower at 5,000 RPM. Riders can expect an exhilarating experience as they twist the throttle, propelling the motorcycle to a top speed of 120 km/h (74.6 mph). The engine's design, coupled with a 6.3:1 compression ratio and an efficient carburettor fuel system, ensures that the RT 350 S is not just about raw power, but also about remarkable fuel efficiency, consuming a mere 3.80 liters per 100 km (61.90 mpg). This potent combination makes for an engaging ride, whether navigating city streets or embarking on longer journeys. The DKW RT 350 S is thoughtfully equipped with features that enhance both comfort and control. Its telescopic front suspension and swingarm rear suspension provide a smooth ride, absorbing bumps and ensuring stability on various terrains. The drum brakes, while perhaps a nod to the era's technology, allow for reliable stopping power, instilling confidence in riders. With a seat height of 750 mm (29.5 inches), the RT 350 S accommodates a wide range of riders, making it an inviting option for those looking to start their motorcycling journey. Its lightweight construction of 162 kg (357.1 lbs) further contributes to its agile handling, allowing for easy maneuverability in urban environments. **

Pros

  • Fuel Efficiency: With a consumption of just 3.80 liters per 100 km, the RT 350 S is economical, allowing for longer rides without frequent fuel stops.
  • Lightweight and Agile: Weighing only 162 kg, this motorcycle is easy to handle, making it ideal for both new riders and seasoned enthusiasts.
  • Versatile Performance: The twin two-stroke engine offers a lively ride, suitable for diverse riding conditions, from city commuting to weekend excursions.

Cons

  • Limited Braking Technology: The drum brakes, while effective for their time, may lack the performance of modern disc systems, requiring extra caution during aggressive riding.
  • Two-Stroke Maintenance: The two-stroke engine demands regular maintenance and a careful eye on oil and fuel mixtures, which may not appeal to all riders.
  • Basic Instrumentation: As a motorcycle from the 1950s, the RT 350 S features minimal instrumentation, lacking modern conveniences that many riders have come to expect today.
