Overview

Introducing the 1984 Jawa 350 Type 638.5 with sidecar—a classic motorcycle that embodies the spirit of adventure and nostalgia for enthusiasts and collectors alike. Positioned firmly in the naked bike category, this model is not just a means of transportation; it’s a tribute to the golden age of motorcycling where simplicity, style, and functionality converged. With its rugged charm and vintage aesthetics, the Jawa 350 Type 638.5 appeals to riders seeking a unique blend of practicality and character, especially those keen on the experience of sidecar riding. At the heart of this motorcycle lies a robust twin-cylinder, two-stroke engine with a displacement of 343 cc, delivering a spirited 26 horsepower at 5,500 RPM. This power might not seem overwhelming by modern standards, but it is perfectly matched to the bike’s lightweight construction, allowing for a top speed of 100 km/h (62.1 mph). The 10.2:1 compression ratio and a bore-stroke ratio of 58.0 x 65.0 mm contribute to its distinctive two-stroke howl, offering a thrilling sound that resonates with true motorcycle aficionados. Riders will appreciate the smoothness of the 4-speed gearbox and the reliability of the chain final drive, which together create an engaging riding experience both on city streets and winding country roads. The 1984 Jawa 350 Type 638.5 is equipped with features that reflect its era while catering to the needs of contemporary riders. The expanding brake system on both the front and rear ensures that stopping power is readily available when needed, giving riders confidence in their handling. Weighing in at 225 kg (496 lbs) with fluids, this motorcycle strikes a balance between sturdy construction and manageable weight, making it suitable for both experienced riders and those new to the world of motorcycles. With a fuel capacity of 17 liters (4.49 gallons), the Jawa 350 is well-suited for longer journeys, where the open road beckons and the call of adventure is irresistible. **

Pros

  • Classic Aesthetic: The retro design and sidecar attachment add a unique visual appeal that stands out in any context.
  • Engaging Riding Experience: The lightweight frame, combined with a responsive engine, offers a lively and fun ride perfect for both city commuting and weekend adventures.
  • Simplicity and Reliability: The straightforward mechanical setup means less complexity and more time spent enjoying the ride rather than troubleshooting.

Cons

  • Limited Power: While adequate for its class, the 26 HP may feel underpowered for riders accustomed to modern, high-performance motorcycles.
  • Braking Performance: The expanding brake system, while effective, may not match the stopping power and precision of contemporary disc brake systems.
  • Two-Stroke Maintenance: The two-stroke engine requires regular maintenance, including oil mixing, which may not appeal to all riders.
