Overview

Step back in time to 1969, an era where simplicity and engineering ingenuity intersected to create the remarkable DKW RT 159. This sleek, sporty motorcycle embodies the spirit of the late '60s, catering to riders who sought both performance and style in a compact package. Positioned as a nimble and accessible motorcycle, the RT 159 was designed for urban commuting and spirited weekend rides, making it a beloved choice for enthusiasts and casual riders alike. With its lightweight frame and classic design, this motorcycle not only delivered on looks but also forged a reputation for reliability and ease of use, making it a staple in the European motorcycle scene. At the heart of the DKW RT 159 lies a spirited 49.6cc single-cylinder, two-stroke engine, capable of producing 5.3 horsepower at a spirited 7,000 RPM. While the power output may seem modest by today’s standards, this little powerhouse pairs perfectly with the motorcycle’s lightweight frame, delivering an exhilarating top speed of 80 km/h (49.7 mph). Riders can expect a lively experience as the engine's punchy performance and responsive throttle provide a thrilling ride through city streets and winding country roads alike. The air-cooled engine, complemented by a carburettor from Bing, ensures that this bike remains reliable and efficient, characteristic of DKW's engineering prowess. The RT 159 also features a well-thought-out chassis and suspension system that enhances its overall riding experience. Equipped with telescopic forks at the front and a swingarm in the rear, the suspension provides a balanced ride, absorbing bumps and imperfections in the road with ease. The expanding drum brakes at both ends offer solid stopping power, instilling confidence in the rider. With a seat height of just 760 mm (29.9 inches), the DKW RT 159 is approachable for riders of various heights, allowing for a comfortable riding position that can be appreciated during longer journeys. Plus, its 13-liter fuel capacity ensures that riders can enjoy longer trips without constant refueling interruptions. **

Pros

  • Lightweight and Agile: At just 85 kg (187.4 pounds), the RT 159 is incredibly maneuverable, making it perfect for both city commuting and spirited rides.
  • Classic Design: The vintage aesthetic attracts enthusiasts and collectors, giving it a timeless charm that stands out in any motorcycle gathering.
  • User-Friendly: The kick start, combined with a low seat height, makes this motorcycle accessible for new riders while still providing an engaging experience for seasoned motorcyclists.

Cons

  • Limited Power: With only 5.3 HP, the RT 159 may struggle to keep up with modern traffic conditions, especially on highways.
  • Drum Brakes: The expanding drum brakes, while effective for their time, may not provide the same stopping power or feel as modern disc brakes.
  • Two-Stroke Maintenance: The two-stroke engine requires more frequent maintenance and attention to fuel mixtures compared to contemporary four-stroke models.
