About CZ 250 MotoCross Type 980.5 1976

The 1976 CZ 250 MotoCross Type 980.5 stands as a revered icon in the world of cross-motocross motorcycles. Manufactured by the Czech company CZ, this machine was designed to dominate the competitive motocross scene of its time. With its rugged styling and robust build, the 980.5 garnered a dedicated following among riders who appreciated both its performance and reliability. As a 250cc two-stroke single, it perfectly blended lightweight agility with the power needed for thrilling off-road adventures, catering to seasoned racers and weekend warriors alike.

At the heart of the CZ 250 MotoCross is a potent 246.20 ccm single-cylinder engine that churns out an impressive 34 horsepower at 6800 RPM. This allows riders to experience a responsive throttle and exhilarating acceleration, making it a joy to navigate through the most challenging terrains. The engine's 11.5:1 compression ratio and finely tuned JIKOV carburetor ensure that the power delivery is both fierce and controllable, allowing for confident handling on jumps and sharp turns. The 5-speed gearbox, paired with a chain final drive, provides seamless gear transitions, empowering riders to exploit the engine's full potential on the track.

The CZ 250 MotoCross boasts a tubular frame that offers both strength and lightweight maneuverability, weighing in at just 99.5 kg (219.4 lbs). The front telescopic oil shock suspension with 200 mm of travel absorbs bumps and impacts, while the hydropneumatic rear suspension with 90 mm of travel enhances the bike's stability and comfort on rugged trails. With drum brakes on both ends, riders can expect reliable stopping power, although enthusiasts may find the need for more modern disc brakes. The bike is designed with an 8-liter fuel capacity, ensuring that the adrenaline can keep flowing without frequent stops.

Pros:

  1. Powerful Engine Performance: The 34 HP engine provides thrilling acceleration and responsiveness, making it a competitive choice for motocross enthusiasts.
  2. Lightweight and Agile: Weighing just 99.5 kg, the 980.5 allows for easy handling and maneuverability, essential for navigating tight corners and jumps.
  3. Durable Build: The tubular frame and robust components are designed to withstand the rigors of off-road riding, ensuring longevity and reliability.

Cons:

  1. Outdated Braking System: The drum brakes, while reliable, may feel less effective compared to modern disc brake systems, especially in high-speed scenarios.
  2. Limited Suspension Travel: Though adequate for the time, the rear suspension travel of 90 mm may not meet the expectations of riders accustomed to contemporary motocross standards.
  3. Kick Start Only: The absence of an electric starter might deter some riders who prefer the convenience of modern starting technology.

In summary, the 1976 CZ 250 MotoCross Type 980.5 remains a classic testament to the rugged charm and performance of vintage motocross machines, appealing to those who value both history and the thrill of the ride.
